It's time to start a build thread on my next project. Like, the Challenger, it will be build over the coarse of a few years as money allows. I still haven't decided exactly what I want the finished product to look like. I know, that's not the right way to start out. The problem is that I like a lot of different styles. I like the stock look as well as the Pro Touring look. I keep going back and forth between these two looks.
Option 1. Stock looking engine, body colored steel wheels with dog dish hub caps and redline tires. I'd keep the GT body side mouldings as well as the DART letters on the quarters and the finish panel on the trunk lid. I'd return the interior to stock except for a volt meter conversion and a small tach on the front of the console.
Option 2. Newer aluminum master cylinder, aluminum intake and fabricated valve covers.(basically try to make the engine not look like a typical SBM) Large diameter wheels. Remove GT side mouldings, DART letters on the quarters and finish panel on the trunk. Interior close to stock except custom gauges in the dash and maybe an aftermarket shifter in the stock console. Rear disc brake kit.

Exactly...I need something to focus on so life doesn't get overwhelming.
My friend Paul came over yesterday and helped me get the engine out. He's helped me a lot this year with everything that's been going on. He's never seen an engine removed this way so it was exciting for him.
I didn't have much time out in the garage today. Most everything is out of the engine compartment except for the brake lines. The grill came out today too.

Be very careful with the pot metal transition moldings near the quarter windows to the stainless pieces, those are almost impossible to find! There is a tab underneath the quarter window stainless that has a tendency to break. I sold one side this year for $125! Also, the door and quarter glass are unique to a convertible too.

I think that is the most haphazard black out picture I've seen yet, thanks for posting.

I did a sedan pro street a few years ago that we painted viper silver then laid out the butt stripe. Took the viper silver put in couple drops of black then put two light dust coats on it. Then cleared the entire car. It just shows up but at times blends in that you can't see it. Customer loved it. I took a scrap piece of metal and colored it in viper silver then tried various ideas with tinting the actual color with blacks & various pearls. Gave them it and let them decide. Wish I had a picture on my phone I could up load. Maybe I'll try from wife's computer tomorrow. Just an idea for you.

I picked up the zinc fasteners yesterday and I'm not happy. When I picked them up, the guy said "These are going to have a little yellowish look to them because our solution is stronger. It resists a 100 hour salt spray vs the normal 40 hour spray." When I got home, I remembered that I had gotten a call that morning confirming I wanted everything yellow zinc plated. I said NO, I want them silver zinc plated. They said "OK, no problem, I thought you wanted them yellow." I think everything was already in the other tank when he called. He probably pulled them out right way after talking to me but the color had already started to change. Some things will be OK. I'm not going back stock with this thing anyway...but some things in the engine comp are going to look like crap next to other things I have planned. I sorted everything out today so I didn't forget where anything goes and I'll deal with the engine comp stuff later. I don't think they were in the yellow tank long but you can really tell the difference when you hold a silver zinc part up to them.

Here's the engine that's going in the Dart. As you can tell, it has been sitting for awhile. I think I pulled it out of my Cordoba in 06. It's a 360 MP short block(roller block)...the 10-1 compression version. It has home ported 360 heads with 1.88in 1.60ex valves. My Cordoba ran 12.70's with this engine. It's going to come apart for all new gaskets and to make sure everything still looks OK. It has very few miles on it so I hope it only needs gaskets. The trans is a 904 that I built in 98. It has a 10" 3500 stall convertor and a TransGo TF-2 shift kit. I started to mock up the new parts. I'm going to get everything fitting before I tear the engine apart. It looks like if I run a thermoquad, I'm going to have to make some kickdown linkage extensions and extend the throttle bracket. If I run a square bore carb, that will get rid the the adapter and lower things a little. There are already two valve cover gaskets on each side and covers are still very close to the intake. I think I'm going to look into those spacers I saw advertised on here. I don't want to grind on the valve covers or the intake. The pulleys are an underdrive version. I plan on running relays under the battery tray for the headlights and make sure the cooling system is designed properly.

I got done rebuilding one of the horns yesterday. Only one of them worked when I tested them. I used Mike Ross' post on how to rebuild a Prestolite horn for reference. It was basically the same procedure rebuilding(just cleaning really)my Sparton horn. First I drilled the heads off of all six rivets and separated the two halves. Once they were apart I drilled and tapped the rivets for 8-32 allen head screws. This wasn't fun because the rivets wanted to spin inside the cone housing. I had to remove them and glue them in the housing. I made two new gaskets from a Christmas box my wife had been saving....don't tell her. I used some C-clamps to hold the horn together while testing. Just like Mike said, all that was needed to get it working again was to sand the contacts. Once it was screwed back together I tested it again just to make sure the center piece hadn't shifted. It still worked so it was ready for paint. Since I'm not going back stock with the car I didn't bother sanding on the allen screws to make them look more like rivets. I'm going to use allen head fasteners on the engine so it will all tie together. This picture was taken right after I sprayed it. It dried slightly less glossy then what it looks like in this picture. I also cleaned up the shifter pivot bracket that bolts to the trans. It cleaned up nicely. I still have to buy a new bushing...the original was in two pieces.

I've been working on the gauges. I still need to get them calibrated and buy a sold state voltage limiter. I was a little too aggressive when I removed one of the connectors from the printed circuit and damaged two of the pins. I read where I could fix them by inserting a paper clip as reinforcement so I thought I'd give it a try. I coated the inside of the pins with flux, inserted a paper clip through the pins and soldered them in. Then I cut off the excess paper clip from either end. I had to grind a little on the back side so the repair would clear the gauge cluster housing. It seemed to work and the pins are now solid. The two pins on the right were loose. You can see they are now filled with solder. The car didn't come with an oil pressure gauge...just and idiot light. I wanted to add an oil pressure gauge but I don't like the look of extra gauges under the dash. I thought about adding one where the idiot light was but there wasn't enough room.(plus I like the idea of the idiot light) I was going to bypass the AMP gauge anyway so I thought an oil pressure gauge would be more important than a volt gauge. I ended up buying a 2" SunPro electric oil pressure gauge and gutted it. I took the mechanism and mounted it in the gauge cluster housing in place of the AMP gauge. The + and sender terminals were the same distance apart as the factory AMP gauge. I had to drill a hole through the cluster housing and the printed circuit for the ground wire. Luckily there was a blank area in the printed circuit where I had to drill the hole. The mechanism just barely clears the blue lense. I removed the SunPro gauge face and used it as a template. I had to cut away some of the original gauge face so it would clear the new mechanism. I also cut off the AMP gauge needle and glued it onto the oil pressure gauge needle. Here is what the back of the gauge looks like mounted in the cluster housing. Next, I cleaned and repainted the inside of the cluster housing. I also made some new gaskets for the turn signal lenses and idiot light lense. Scrap foam from DMT gasket kits comes in handy for things like that. I tried repainting the gauge faces but I didn't have any luck. My plan was to paint the faces white, then spray SEM trim black over it. Then I was going to wipe off the black from the raised areas with lacquer thinner. I stripped the faces and painted them with single stage Centari with a Prevail sprayer. After four days I sprayed them with trim black. Four days wasn't long enough because the white paint lifted as soon as I sprayed the pieces with the trim black. I stripped the faces back down to bare metal and purchased a white overlay kit. I'm not sold on the white gauge look so this may just be temporary. Since the interior is white, there's a chance it may look OK. I also bought an odometer reface kit. Originally I bought one for a standard dash E-body since they didn't offer one for the Dart. The size of the overlays was correct but the Dart's odometer spins in the opposite direction so the numbers were reversed. They sent me an E-body Rallye gauge kit as well as a B-body kit to try. The E-body Rallye gauge kit worked great. Here's what the gauge cluster looks like now. I'm going to wait for final judgment until I can see what it looks like with the entire dash assembly together. I've seen a picture of the gauges at night and they look cool with the blue light on them. I'm just not sure about how they'll look in the daylight.

Here is a thread about the bearing on FABO. There is also one on CC.com http://www.forabodiesonly.com/mopar/show...+column+bearingAfter the rust is gone, the acid is neutralised with baking soda and water. The parts will flash rust imediately after being cleaned this way. I found that if I soak them in EvapoRust for maybe 5-10 minutes, they won't flash rust. I rinse off the EvapoRust and dry them with compressed air. They end up looking like the one picture I posted. After that, they were sprayed with SEM self etching primer.

Just a small update. There is a company called Illumin8s that sells a multi function LED parking light kit for Challenger, Cuda, Charger and some GM products. You may have seen this video before but here's how they work... http://www.youtube.com/watch?v=nactAwM4WtwThey didn't make a kit for the 68 Dart so I contacted them about making me one. I sent them one of my parking light housings and they designed a kit that they are now going to offer. Here is what it looks like installed in the housing. The LED just plugs into the existing socket...there is no modification to the stock wiring. What I'm going to do is rewire the parking lights and hook them up to ignition "RUN" power. They will act as a daytime running light this way. Since I'm concerned they may be too bright at night,(they sit so high up on the grill)I'm also going to run the power wire through a toggle switch. I'll install a stock switch and bezel in place of the cigarette lighter. This way, I can turn them off at night. Now I just have to come up with something for the tail lights. There is an LED kit available for the 69 Dart but nothing for the 68.

Here's an update on the dash assembly... There was a bad spot in the dash frame. I separated the outer skin from the lower frame so I could clean out the rust that had formed in between. Then I cut out the bad section and made a repair piece. I had the frame blasted. Weld through primer was used between the outer skin and the lower frame before it was welded back together. I sprayed the frame with self etch primer, Rustoleum fine texture black and satin clear. It's just slightly more texture then it had originally. I wasn't happy with how the top looked. I thought the texture would hide some minor pitting but it didn't. I stripped the top back down to bare metal, applied a thin layer of filler and sanded it back down. It looks good now. I sprayed the two lower pads with SEM Landau Black. If reproductions were available I would have replaced them. The vinyl is wavy in a few spots but there are no cracks. It will do for now. Having them redone will be a winter project down the road once the car is driveable. The upper pad is a new BE&A piece I bought from Dave at Roseville. It fit pretty good. There is a slight hump in the middle where it isn't sitting down against the frame. It should look fine in the car though. All the switches were sent out to JS Restorations for a rebuild. The ash tray was hanging very low. I had to add some spacers between the dash frame and ash tray bracket to lift the tray up tight to the lower pad. The dual speaker bracket fit great and there is plenty of room between the speakers and the heater controls. I cleaned up the dash harness and replaced a few wires and terminal ends that were chewed up by mice. The harness was really dirty but was in good shape otherwise. Right now I'm at a stopping point. I have to send the radio out for an FM conversion and I have to buy new dash bezels. I'll post more pics once it's completely done.

Still working on the console. I cut the factory bracket off the floor since the new shifter requires a much shorter bracket. I used a steel plate and some wood to mock up where I needed the shifter to be. I ended up moving it about an 1/8" to the passengers side from where I originally intended to put it. With it slightly farther to the right side, I can bolt an extension onto the side of the reverse lockout lever. Otherwise I would have had to weld an extension onto the top of the existing lever. With my measurements taken, I started building a template out of cardboard. My father-in-law calls that a CAD system.(cardboard aided design) I reinforced the template so it would support the weight of the shifter and made sure the design was going to work. Then I started making the bracket out of 18 gauge sheet metal. I cut the cardboard template apart and transferred it to the sheet metal. I bolted a 30" sheet metal brake to my work bench that my father-in-law had given me a few month prior. This was my first time using it but I think the bracket turned out nice. Once I have the final shifter position marked, I'll drill the holes and have nuts welded on the bottom side.

I wasn't happy with the way the gauge cluster turned out. The vinyl didn't stick to the raised numbers/letters very well. The worst looking piece was the large outer panel. I decided to redo all of the pieces using a matte vinyl instead of gloss. The matte material will hide any imperfections better. I took the upper panel to my father-in-laws house and we machined off all the letters/numbers. I put a thin layer of filler over the area to cover the machining marks. I sprayed it flat white. Since I was installing the vinyl on a flat surface, I had the wording changed to reflect the change I made to the cluster. I had the "OIL" wording moved over to where the "ALT" wording originally was. Then I had "WARNING" placed above the idiot light. Here are the gauges after replacing all the vinyl overlays. I also ground off the "D" and "C" from the alt gauge face. I had "0" and "100" put in their place for the oil pressure gauge. The graduations on the original face match the graduations on the aftermarket gauge face, so it should read accurately.

I ordered a headlight relay kit from a member over on FABO and it arrived on Saturday. At first I mounted the relays on the inner fender below the battery tray. I thought they would be hidden there but I was wrong. I thought about building a cover that would hang down underneath the tray but didn't think that would look very good. With some advice from other online friends, yesterday I remounted the relays to the underside of the tray itself. I like this a lot better. You can barely even see them now. With the rest of the engine compartment assembled, you probably won't be able to see them at all. I'll be mounting a bus bar to the underside of the tray as well. I'll run a wire from the starter relay to power the bar. When I install relays for the convert top motor, I can tie right onto the other terminals on the bar. While I was at it, I also mounted the oil vapor separator to the PS inner fender. The PCV breather will be at the back of the PS valve cover. The hose will go right into the tank and then go right into the carb. It should look clean this way. I will be removing the lettering from the tank before it's installed permanently. I was a little quick to get the K-member powder coated over the winter. There are some more modifications I want to make so it will need to be coated again. I bought a torque strap for the engine but ran into an issue with the K-member bracket. The pinch weld lip on this K isn't wide enough to mount the bracket. The holes that need to be drilled would be right at the edge of the lip. I thought about widening the lip but decided just to have the bracket welded to the K instead. I also decided to add a skid plate to the bottom. I made one out of cardboard just to see what it would look like. Then I made it out of metal. The back curved section is open right now. I wasn't sure how to make that section. I ended up just cutting out a strip of metal and bent it to fit the area. It will be welded onto the back side once the rest of the plate is tacked on.

I haven't posted anything in awhile but I'm still working on some things. I started working on the engine last month. I think I mentioned earlier that the short block is a MP piece I bought back in 2000. The short blocks were made from reconditioned non Magnum roller blocks. It's the 10 to 1 compression version. I believe there was also a 9 to 1 version. The engine has been sitting since 2004 or 2005. I previously ran a Weiand X-cellerator single plane intake on the engine. Last fall I bought an Edelbrock RPM Air-Gap for it. I pulled the Weiand and started mocking up the intake and carb but ran into an issue. The secondaries on the carb would hit the intake. It looked like the intake was cast wrong. After talking with tech support a few times, they had me send the intake in for them to look at. They ended up sending me a new intake but by that time it was the middle of winter and I had moved on to other things. Last month I moved the engine over to my place. I pulled the plastic off the engine and found a mouse next in the valley. The nest was made from grass clippings so I knew it hadn't been there long. It wasn't there last fall when I was test fitting the new intake. I vacuumed up the nest and put the engine on the stand. I pulled the heads, water pump and front cover. I didn't want to spin the engine on the stand incase there was crap in the pan. I pulled the pan with the engine upright and removed the windage tray. Sure enough, there were some grass clippings and mouse foot prints on the tray. There wasn't much of anything in the pan though. I think I got lucky and caught it early. Other then the nest, the engine looked really good inside. Everything still looked clean without any rust from sitting. Then came the task of cleaning up the block. There were a couple layers of orange paint and layers of dirt, saw dust and oil to remove. What a nasty, crappy job that was. I think it took at least four cleanings to get everything off. Even after wearing gloves and goggles, some paint stripper would end up on my skin and start burning. I'm glad that job is over! I installed the timing cover and put a new water pump on. Then I primed the everything. After that I moved on to the oil pan. The pan that was on the engine had seen better days. The sides were heavily pitted and would have taken a lot of work to refinish. A friend of mine had a 360 pan he wasn't using so he donated it to the cause. I saw and old Car Craft article on making a baffle for the stock oil pan. It didn't look too difficult so I thought I'd give it a try. I made a template out of card board and taped it onto the pan. I test fit it a few times onto the engine to make sure it cleared the pickup tube, then I transferred the template to a piece of metal. I taped the metal baffle to the pan and test fit again. So far so good. I had clearance around the pickup tube and nothing was hitting. I soaked the baffle in EvapoRust and then added some drain back slots. Here is the baffle welded in place. It works really good on deceleration but doesn't seem to do much on acceleration. I could have gotten the clearances tighter to the pickup tube if I would have had a bare block to test fit it on. I would have been able to look down through an empty cylinder and see how close it came to hitting. The pan isn't installed yet so I guess I could still add some metal around the back if I found someone local with a bare block I could borrow. That's all the progress I have on the engine right now. I need to take the heads in and have them looked at. They only have a few hundred miles on them but I did the valve job and guides when I was in school. I want someone to double check my work so I don't have any issues down the road. I also need to get the intake surface of the heads milled down a little so the intake sits a little lower on the engine. I could barely get the intake bolts started when I was test fitting things.

I don't know if anyone is following this or not but here's a small update. After waiting more than three months, the fasteners finally came back from the platers. I had then done at a local shop but the color turned out wrong. They came through with a yellow tint. I sent them to another place to get coated the correct silver color. This past week I dropped off the cylinder heads at the machine shop to be checked over. I'm also having some material removed from the intake surface of the head because I could barely get the intake bolts started. The intake needs to sit down a little bit lower. Since the fasteners came back, I was able to mount the LCA/strut rods to the K-member. I also temporarily put the 2" drop spindles in place. I got some work done on the aluminum pedal covers. I did some sanding on the gas pedal cover and mounted it to the original pedal to see what it would look like. Right now you can see the plastic gas pedal through the holes in the cover. I'm going to paint a thin piece of aluminum and put it between the pedal and the cover so it doesn't look cheap. I also got the brake pedal cover made. I was able to put a curve in the aluminum so it matched the curve in the brake pedal arm. I think there needs to be some more grip on the pedal so my foot doesn't slide while applying the brakes. My plan is to put some 1/2" rubber pieces in the holes. The rubber will stick up maybe 1/8" from the surface of the cover. That should give me the grip I need and not change the look of the cover. I think they are turning out good so far. The best part is I only have a few dollars in the attaching screws. The rest was free.

I didn't do much work on the car over the winter. Now that the weather is warming up, I've gotten some things done. If you remember, I'm adding engine compartment braces to the Dart. I made some aluminum brackets in order to attach the braces to the factory pinch weld. I sprayed the brackets with a matte clear but wasn't happy with them. I stripped the clear coat and decided to polish them instead. I test fit them with some nuts on the bottom side of the pinch weld. The nuts were more visible then I thought they'd be and they looked cheap. I ended up making another bracket to go on the bottom side. The lower brackets are threaded. Basically, the pinch weld will be sandwiched between the two aluminum brackets. I think this looks much nicer. I'm going to use some polished button head bolts to attach them to the car. I liked how the gas/brake pedals turned out but I wanted something that would give me some traction. Plain aluminum might get slick in certain conditions and not be the safest on the street. My father-in-law cuts up old tires and uses them for traction around the yard during the winter. That gave me an idea. I used an old socket(with the edge ground to a sharp point)to punch holes in an old tire sidewall. The rubber plugs it created will go inside the holes of the pedals.(rubber will stick up higher then the aluminum)

The engine is now back together as well. I had the heads looked at by a machine shop. The valve seats left a lot to be desired so they ground those and machined the top of the guides for positive valve seals. I also had them machine the intake face of the heads. The heads have been worked on a couple times and the block has been decked. This added up to having intake fitment problems. Having the heads machined should have let the intake sit down lower on the engine. Previously, the holes in the intake were too high and it was hard getting the bolts started. After having the heads machined, the intake still didn't fit. To make a long story short, I tried two different Edelbrock intakes with the same result.(Air Gap and a Performer) I tried a Weiand X-Celerator and it fit perfectly. I ended up having my Air-Gap machined to fit the engine. I bought a new set of rocker arms/shafts and reinstalled the cam block-off plate I had made years earlier. Before I installed the intake, I bought a Pertronix distributor and checked to see how it fit. After reading multiple posts on this site, I made some changes. First of all, there was a lot of up and down movement in the dist shaft. I took the collar off the bottom and added another shim. This took most of the movement out but still left a little bit for thermal expansion. Next, I looked at how the drive lug fit into the intermediate shaft slot. There was a LOT of slop between the two. I noticed some wear on the edges of the intermediate shaft slot so I bought a new one. The fit was slightly better but there was still way to much slop. With advice from this site, I peened the four corners of the dist drive lug with a punch. This expanded the metal and tightened up the fitment. Lastly, I installed a shaft collar onto the bottom of the dist shaft to keep the gear from "bouncing". Then, I installed the intake manifold. At this point though, it had gotten cold so I couldn't paint the engine. I test fit my TTI headers and ran into a couple issues. The main issue is that my 360 came from a truck. The truck blocks must have an extra boss on the PS that the car blocks don't have. This extra boss interfered with the center header tubes. Some work with my angle grinder took care of the interference. On Saturday, it was finally warm enough to paint the engine. On Sunday, I attached the trans and dropped the engine onto the K-member. I'm tired of seeing orange engines.(unless they are in stock restored cars) It's kind of like seeing a small block Chevy in every hot rod. I decided to go with a cast iron looking paint. I'm not 100% sure about it yet but I think it will look good in a blue engine compartment. The natural aluminum valve covers don't look the best IMO. A friend of mine photoshopped them black for me. I think they look a lot better black. I plan on running black accessores as well so it should all tie in together. The trans cooler lines interfere with my aftermarket shifter bracket and the TTI headers. I think I'll need to make some custom cooler lines out of braided hose. Once I get the radiator fitted, I'll be installing the engine to test fit some things. I think the headers will be too low. If that's the case, TTI makes a shorty header that should give me more clearance.

I've been using bulkhead connectors to get thru the radiator support, to the trans cooler on the last 2 builds that I have done. I use hard lines on the engine compartment side, and run them down the drivers side frame rail, behind the steering box. It gets them completely away from the exhaust and linkage. I then use steel braided flex lines to go from the end of the hard lines, over to the fittings on the transmission. They need to flex on that end, so the don't crack. Now I gotta figure out how to make trans cooler lines for the 545RFE going in my 70 Duster! Good luck, and I think your motor looks GREAT. I vote polished valve covers.

You should be able to buy 60" and 72" lengths of 5/16 steel line at a parts house, with the ends already flared. You'll have to cut one end off, and install a female fitting on one end. I used the end with the flare left on the bulkhead fittings, and re-flared the other end for whatever fittings I used on the braided flex hose. I used the rubber lined clamps to attach to frame rail. The place here in town that makes hydraulic hoses gave me a handful of fittings for the braided flex hoses, and I went home and decided what I wanted to use for the best fit. I cut the hose to the lengths I needed, and installed the fittings I wanted to use, and then made a mark with a Sharpie at the fitting and hose. Took em back and they crimped the fittings on where I marked them. It worked slicker'n cat poop on linoleum!

Last night I cleaned up an old mini starter from a 92 Dakota. I thought it was going to be a direct fit but it wasn't. I had to grind away a bump on the block as well as take some material off of the starter case. I had a mini starter on this block in the past which makes me wonder if I had it installed correctly the first time. I started out today by cleaning up the ps box and mocking it up on the K-member. It was very close to hitting the headers but I knew the engine wasn't in the correct location just sitting on the stand. I decided to stay with power steering. I was originally going to install a manual box but decided against it. I'll eventually send the ps box to Firm Feel for a stage 3 rebuild. I temporarily installed an old fuel pump because I know the alternators get fairly close to them. I'm going to mock up a smaller denso alternator and wanted to make sure everything was going to clear. Now that those parts were installed, it was time to lift the body over the engine. I read a post that said the Pertronix distributors don't fit the A-bodies. I was worried so I put the wiper motor in place and checked the clearance. It's very close but it should clear if I use 90 degree plug ends. After getting the trans mount fastened, I checked the ps box clearance at the header. There is plenty of clearance now. I've got about 2 3/4" of clearance between the water pump pulley and the radiator core. I was planning on running a Taurus electric fan. I'll have to see if I can find a depth measurement on that fan/shroud combo. Rock Auto shows length and width but not depth. If it's not too deep, it should fit this radiator nicely.

Since I don't have to worry about powering an electric cooling fan, I can get away with a smaller amperage alternator. I don't want to have any problems with amperage at idle so I went with a Denso alternator. I was able to get my billet brackets to work with the Denso. I just had to machine custom length spacers so the pulleys would line up. I also decided to stick with power steering. That meant buying the corresponding PS brackets and pulleys. Luckily, the company I bought them from was very nice and let me send back the single groove crank pulley since it was unused. The PS reservoir cover looks out of place right now but I see that Summit sells a billet cover for it. That will look much better. I also have to figure out a cover for the alt pulley. It looks really bad right now. I might have to make something myself. Another project I've been working on is the air cleaner. I wanted something custom that you wouldn't see very often. The first order of business was just finding something that would fit with my limited hood clearance. I bought a $20 generic 14" air cleaner from Summit. It has a 1" drop base and came with a 3" filter. The problem is that the Edelbrock carb I'm using has an electric choke which really limits the amount of drop you can have in your base. The maximum drop that you can fit on an Edelbrock carb is 3/4". Mine was 1". Since I can't weld, I went over to a friends house and he helped me modify the base to fit the carb. We cut open the base, bent it up a little bit and welded it back together. Now it clears the choke cover. The next problem was that with that modification, the air filter didn't sit down flush onto the base. I took care of that by just grinding away some of the rubber on the inside of the filter. With the radiator removed, I could check my hood clearance. That extra 1/4" came in handy since I'm very close to one of the underhood braces. I could have installed a shorter filter but I really like the look of the 3" and wanted to make it work. After I knew it was going to fit, I set out to make it look better and not so generic. I did a lot of searching online for air cleaner ideas and finally came up with something I liked. First, I bought a piece of .025 aluminum that was 3" tall and 4' long. I played around with the hole layout to see what looked the best. I used a 1 1/4" hole saw to drill 14 holes along the entire length of the aluminum. I bought a dimple die when I was making my trans cooler mounting bracket so it was just sitting in the tool box. I used that dimple die to dimple all 14 holes. Then it was just a matter of bending the aluminum around the air cleaner. I didn't know how easily it would bend with all the dimples in it but it ended up bending really easy. To hold it all together I just cut the aluminum strip to length and riveted the ends together. The aluminum piece fits inside the upper/lower lips of the air cleaner. I like how it looks. Before you question how well it flows, there are 14 holes all the way around it. That should be more area than a factory dual snorkel air cleaner.

A couple years ago, I gave a C-body 8-3/4 housing to someone to have shortened. I never got it back. They stopped answering emails and phone calls went unanswered. It was a freebie when I bought the Dart so I wasn't out any money, but it was still frustrating. This year at the Nats, I talked to the guy I bought the car from and told him the situation. Since scrap prices have been low for a long time, he still had some wide 8-3/4 housings sitting out back. He said I could stop by grab a new one. I found someone else local that has the equipment and gave him the housing. He was really busy but worked it in his schedule. I got it back last week. Stock A-body width is 52-5/8". I had the housing cut to 51-1/4". That's the minimum length Dr Diff recommends with his 1/2" spring relocation hangers. Any narrower and the outer U-bolts would hit the housing ends. Last Sunday I ordered axles, rear disc brakes, E-brake cables and spring hangers from Dr Diff. Everything got here on Thursday. Talk about great service. I got the brakes all mocked up and they fit really nice. It's nice to buy something and have it fit like it should the first time. I ordered new brake lines from Fine Lines a couple years ago. They cut the axle brake lines short for me since I told them I was going to use rear discs. At the time I was planning on using a Wilwood kit. The Wilwood kit must use shorter brake hoses because the lines are too long right now. I need to find someone that can double flare stainless lines so I can cut these shorter. I'd like to mount the brake hose bracket on the back side of the housing. I think it will look nice and be a cleaner install on the back side rather than on the top. My only concern is the shock clearance. I'm not sure how much clearance there is between the axle tube and the shock body. I don't want the hose/line to get in the way. The E-brake cables that showed up are really nice looking pieces. I guess I was expecting some generic cut-to-fit type cable but these are super nice. I need to weld a clip to the front of the PS axle tube to hold the cable since this replacement housing didn't have one there. Once the lines are hooked up and the clip gets welded, I can mount the assembly under the car and measure for wheels/tires. Then it will come back out so I can blast, smooth and paint the housing. Now I need to save up for the front brake kit... It's kind of funny the at 11.7", the rear rotors are larger then my Challenger's stock front rotors. The Dart originally came with 4 wheel drum brakes and no front sway bar. It should stop and handle a lot better once I'm done with it.

I worked on the springs today. The oval track springs use the larger B and E body shackle bushings. In order for them to work on an A-body, you have to get special bushings OR sleeve either the spring or the bushing. I have new A-body bushings here so I decided to sleeve the spring.
I went to the hardware store and bought a couple 1" OD black pipe sections. The OD was a little too big to fit into the rear spring eye, but the inner diameter was perfect for the A-body bushings. I went over to my father-in-law's house and used his lathe to cut down the outside of the pipe so it could be installed into the spring.

It looks like it's been awhile since I posted anything on this car. Not much going on with it lately. I have been struggling to get motivated to work on it actually. A few things have been done since I last posted but nothing major. Last year I was playing around with the computer and did a quick rendering with the paint program. I found a picture I had taken at Carlisle a few years ago. It was of a 69 but the color was close so I started with that. I got rid of the 69 side markers and pasted on some 68s. I did an online search for cars that had similar wheels to the ones I'm thinking of running. I found a Camaro picture that was framed the same and pasted the wheels onto the Dart picture. Finally, I put some carbon fiber stripes on the back. I think it looks pretty good! This is basically my idea of what I want the car to look like. I read a post in the race section about proper trans cooler mounting. I realized I had mine mounted incorrectly. I flipped it around so the fittings were pointing up. This way the cooler stays full of fluid and doesn't develop an air pocket in the upper passages. I had to redo the lines so I ended up running them both to the drivers side. I was going to run into issues trying to get a cooler line past the lower rad hose. With both of them on the drivers side, I have more room.

I rebuilt the steering column with the intent of swapping from power steering to manual steering. After the column was done, I changed my mind and decided to keep the power steering. I pulled out the column shaft and swapped in the original lower shaft. I wanted to hold the two pieces together tightly but still allow movement in an accident. This is what I came up with... The upper shaft just has indentations where hot plastic was injected into the assembly to hold it together. After marking the correct location, I drilled all the way through the upper shaft with an 1/8" bit. My father-in-law had some scrap lexan lying around that he thought would work as a "pin" to hold the two halves together. He turned a couple scraps into "pins" and I pounded them through the assembly. We heated the head of a nail with a torch and used that to melt the ends to lock them in place. Finally, I drilled through the center of the pins with a 1/16" bit. The shaft is held tight but it should easily collapse in an accident. Last fall I shipped the steering box to Firm Feel. They did a stage 3 rebuild on it. I was able to get it painted and installed on the K right before it got cold. A couple weeks ago I got this next piece done. I'm going to use a reproduction Tuff wheel on this car. I bought an adapter at the Mopar Nats last year. The problem is that the 68 column was never designed for the adapter. The 68 column is smaller in diameter then the 70 column that the adapter was designed for. The upper column rubs on the inside of the adapter. I had to sand the adapter to clear the column. That wasn't a big deal. The issue is that the adapter really looks like crap on the smaller column. Here is what the adapter looks like on a 68 column. UGLY!!!! I was looking at a Dart under a tent in the swap meet at the Nats last year and noticed it also used the factory tuff wheel adapter. That car had an aluminum trim ring on the bottom of the adapter to help transition the two pieces. It really looked good. The owner said he bought the car with that trim piece already installed so he didn't know who made it. I took a couple pictures of it and made my own. I started with a 5x5 piece of 1/2" aluminum. After cutting out the center hole on my father-in-laws mill, we mounted it to his lathe and turned the outside to the correct diameter. Then we readjusted the lathe and machined an angle into the piece. Here is the trim ring test fit onto the wheel adapter. I still needed to do some hand sanding on the trim ring when I took this picture but this is basically what it looks like installed. I really like it. It makes the adapter look like it was made for the earlier columns.

I've been putting off working on the convertible top mechanism because it was intimidating. Finally got to the point where I needed to work on it so... I started out by taking a lot of pictures and measurements. There are two main adjustment links at the back that have a lot of adjustability. Before taking the bolts loose, I staked both sides of the links so I could line up the marks during assembly. With all the measurements and pictures taken I took the mechanism to the back yard and power washed it. Here are all the pieces of the top mechanism laid out after disassembly. I started with the bows since those looked simple. The tack strip material on the sides were in decent shape but there were signs of rust underneith them so they had to be removed. The factory installed the tack strips into bare metal bows...then they were painted. The tack strip material in the rear bow was in bad shape so that was removed as well. I'll talk to a convertible top installer and see what they recommend before I reinstall any new tack strip material. Original paint underneath a side bracket. SEM Trim Black looks like a perfect match to me. After the three bows were sanded down and painted, I turned my attention to the front header. It looked like it was in really good shape with no sections rusted through. After taking out the old latches though, a bunch of scaly rusty crap came out of the hollow inner cavity. I bought a cheap endoscope for my cell phone so I could see deeper inside to assess the rust. It looked pretty nasty. I found a good deal on EvapoRust at Walmart.com believe it or not. A 3.5 gallon bucket was only like $46. I bought three. Then I picked up some scrap 2x4 / 2x6 and OSB from work and built two boxes. One to soak the header and one to soak the side mechanisms. I lined the long box with plastic and soaked the header in the EvapoRust for close to 24 hours...checking it and hosing it out periodically. The results were impressive. before after After the EvapoRust bath I sprayed the inside with Ospho(actually Concrete and Metal Prep which is the same thing) which turned the remaining rust in the tight seams black. Then I masked off the latch openings and poured black paint into the cavity. I poured a lot in and made sure I got everything inside coated. Then let the excess run out the other end.

That will help a bunch when it's time to do my Roadrunner. Looks like it won't be long until you'll be in the "Bolt it together and don't skin it!" phase.

The car is back home. I need to let the paint sit for about 120 days before I can wax it. I'll probably wait that long before I start bolting on parts to the exterior. Until then I'll keep busy by installing things under the car and getting the glass into the doors and 1/4s. Once the glass is in and I make sure the doors don't need to be readjusted, the inner fender splash shields will be installed and undercoating will be sprayed in the wheel wells. Once the outside temps are a little warmer, I'll start installing the butyl sound deadener to the interior floor and inside the doors. Late last week I installed the body plugs and set the tail light wiring in place.(man these A-bodies have a lot of body plugs...way more then my Challengers has) Saturday we had warmer temps so I decided to get the rad support blackout done. I set the old grill and headlight bezels in place so I could see which areas were visible through the grill. I didn't like how the factory blackout went all the way up to the top of the latch support so I decided to leave that area body color. The bottom of the latch support can be seen through the grill so the bottom was sprayed but not the top. That was all the time I had to work on the car on Saturday. That afternoon I went to Disney on Ice with my wife and daughter. Then we rushed home at night to beat the severe thunderstorms and tornados passing through the area. On Sunday I realized that the body shop had filled in the washer bottle mounting holes. I had them fill some extra holes on the inner fender but for some reason they filled all of them. After re-drilling those holes, I mounted the headlight relays to the battery tray and install that. Then I started running the new headlight wiring. The wiring was a little more difficult then I had expected though. I must not have tried fishing the plugs through the headlight bucket support during the test fitment stage. The aftermarket plugs are too thick to pass through the limited space available. I had to get out the cutoff wheel and cut a notch in the bucket support. About 1/4" more room was needed. Now the plugs will easily pass into the back of the headlight area. Once that was done, mounting the buckets and all the adjuster hardware went pretty quick. Later on Sunday I installed the brake/fuel lines and rear axle bumpers. Next thing to work on is cleaning up the gas tank and getting that installed.

(man these A-bodies have a lot of body plugs...way more then my Challengers has) Why do you think A-bodies are so light? After re-drilling those holes, I mounted the headlight relays to the battery tray and install that. I had to get out the cutoff wheel and cut a notch in the bucket support. About 1/4" more room was needed. I would have agonized over doing this to a beautiful, newly painted car.

Still waiting until the 120 day mark so I can wax the engine compartment and start assembling things in there. For now I've been working on applying the sound deadener to the floor. I was concerned about the garage temps being in the 30s/40s but it installed easily. I was planning on using Kilmat but ordered some stuff called Siless by accident. It's 80 mil, made from butyl and came in the same quantity as Kilmat so I used it. I covered the entire floor pan and up the firewall to where the factory insulation starts. I installed some under the rear seat but just in the middle. That's where the resonance was. The area above the frame rails were solid so I didn't think I needed anything there. The section of the floor pan where the convertible top will sit sounded really hollow so I installed some there as well. I put a couple strips of sound deadener on the seat back brace that spans between the wheel wells. It sounded really hollow too. The metal wire covers along the rocker area were really beat up and rusted through in a few places. Replacements seemed really expensive for what they are so I made my own. I just bought the thinnest sheet metal the metal company carried(20 gauge) and drilled some holes along the length. Then I dimple died it for strength. I thought about different ways to attach it but ended up just using the sound deadener itself to hold the pieces in place. Finally, I put some aluminum tape on all the seams. The edges of the sound deadener are exposed and sticky. I put the tape on it so the carpet doesn't stick to the floor when the temp warms up. I also got the 1/4 windows installed. What a PITA. I downloaded the 67 and 69 service manuals(the 68 manual isn't online) and read how they are supposed to be installed. The instructions left a lot to be desired. I ended up having to completely remove the rear stabilizer and unbolt the front track in order to move the glass forward inside the 1/4 so I could get the rollers attached. Before I could do any of that though, I had to sand/polish the stainless weather stripping channel at the leading edge of the glass. On my Challenger, the stainless was still attached to the glass so I carefully polished it as an assembly. On the Dart though, the glass setting tape had lost its hold and the stainless was loose. The convertible uses rivets to hold the stainless to the lift bracket at the bottom. Once I drilled off the rivet head I was able to tap them out and remove the stainless piece. Here are the rivets holding the stainless to the lift bracket. I discovered that I could drill and tap the lift bracket holes for some 8-32 button head screws. This made reattaching it at the base easy. There was still the issue with the glass setting tape though. A few well respected people on this site said they never really had much luck using that stuff so I was a little nervous. While looking up weatherstrip adhesive online I stumbled on a product called "windshield and glass sealant". Its designed to fix leaks between glass and rubber gaskets. The tube was only $6 so I thought I'd give it a try. The glass setting tape was still well attached to the stainless...it had just come loose from the glass. So, after cleaning the old tape and the glass, I ran a bead of the sealant on the leading edge of the glass. Then I pushed the stainless in place. After attaching the bottom with the allen head screws, I wrapped tape around the glass to hold everything stationary while the sealant dried. So far it seems to be working great. If it fails, I'll just have to install new glass setting tape. The windshield sealant is basically thin, flowable silicone. It's quite a bit thinner then regular clear silicone you find in a big tube. Here are the button head screws used to attach the stainless to the lift bracket.

Nice work!
I totally agree with your color choices on the wiper motor. It provides nice visual continuity with the blower motor and master cylinder. Agreed & that dash looks great!

Good looking car. years ago I had B5 with white 1969 Dart GT conv.
simple 318 car . But I liked it. A LOT.
Midwest rust took its toll on it though. I ended up parting it out and sent the shell to the crusher
Enjoy life today, It has an expiration date
