I just got into a 1938 coupe project and did not konw what I was getting into. need help on finding information about building car and repairing issues with car. Car was a quick purchase and now as I have time to look over I have found many many many issues with the car. motor mounts, trans issues, and drive shaft issues.
bigges issues is steering and bad vibration when accelerating.
steering system- 5 inch drop with disk brakes but only turn 1/4 of way to the left and full movement to right. steering colum hits exhaust manifold. etc.
bad vibration when accelerating or letting off of the gas.
car has a 350 engine with 400 turbo trans and factory rear end.
Wanting to restore and turn into a great project, first of many mopar projects .

The vibration could be drive shaft bent or maybe its not phased ..
Could have a bent wheel, axle
I'd look there for those items

hello! Guy buys a primered, incomplete running rod and has issues. Sounds like he doesn't have the bucks to do a complete rebuild all at once. First, the steering issue means you shouldn't even drive it on the streets. Let us know if it's a steering box with linkage or a rack and pinion setup. Pictures would be nice. Next, inspect every inch of the frame, drivetrain, brake system and wiring. Look at the welds, the way things are put together and for any loose, leaking cut up or rusty parts. It sounds like someone didn't have a level of workmanship that you should trust your life with. We can help, just take it a step at a time.

Thanks I know I will have alot of questions and appreciate all the feed back and help.
just pulled motor trans out of the car tonight, putting out for sale. no need to keep a chevy motor in the car, going to pull the body and other items Thursday night so i can see what I am up against. Alot of my friends are chevy guys and its the same car and same items they do to each of them. had to get something different that has some class to it. I might be over my head alot but i am hoping this will turn into a great project. $$$ is no option but I have told myself that I am going to do the car myself. the more I look and find It looks like a very bad hack job. the guy who started really left me with alot of work.

Look at this thread for some pics on an F/M/J install: https://board.moparts.org/ubbthreads/show...e=1#Post5021197Also, it's not likely as bad as all that. By the looks of things, if you have to you could probably chop the frame at the firewall and slide an early Dakota setup right in between the rails. A couple hundred buck and a few hours and you won't be feeling like you're dealing with a bad hack job anymore. If the current frontend stuff IS MII, you can likely flog it for a few bucks as well.

Raw material, to be sure! Looks like a dropped axle on parallel leaf springs in front. Doubt that has a rack and pinion, but you never know! The steering column looks like an 80s Chevy, probably the same donor that gave the engine/trans. Those columns should just keep spinning in either direction, so the issue is probably the box or linkage. Normally on a rear steer box, the box itself has internal stops. You could disconnect the linkage and turn the box both ways to find the center point and check that with where it is when the linkage is connected and the wheels straight ahead. However, if you are going to change stuff, the main things to remember before tearing it apart is where the sheetmetal attaches, what the wheelbase and track are, and what you want the final ride height to be. Figure all that out before cutting! Full frame swaps are a lot more work than you would think, so that leaves using the current frame rails with something attached, or a subframe graft. Popular stuff is Mustang II based (examples only) http://www.streetrodengineering.com/Products/mustangllifskits.htmand http://www.progressiveautomotive.com/street.htmOthers include Pacer, Volare, vette, jaguar, and any other OE that may fit. Have you read about LAWFISH's project? It ought to give you lots to consider.. https://board.moparts.org/ubbthreads/show...e=1#Post5088072

Looks like the stock front axle. If so the metal bushings in the spring could be all wore out, they are supposed to be grease regularly. Also, king pin bushings could be shot too, again they are metal and supposed to get greased often.
Somewhere I have the FSM for a 38 Plymouth, used to own one.

starting going over the car today since the motor and trans are out. has a 5inch drop axle with parrelle leaf springs. it appears the steering system along with the engine and trans came out of a chevy van... where do people get ideas for taking items from a van to make project. the master cylinder for the brakes also came out of the van. steering colum is sto short and does not connect properly and the steering box it at a very bad angle. looks like the steering system is not set up at all. the location and set up alonly allow the steering to turn to the right and I get 1/4 of the movement to the left. I am going to take some more pictures on Friday. Motor mounts and other items are not mounted properly either. right side mount is welded 1/2 inch lower than left side. Drive shaft is home made and welded in the middle. and way out of round. Found my vibration when driving. going to michigan to look at a drive tran, engine and trans. found on-line not a hemi but getting back to the mopar drive tran.
will keep you posted.

welded drivshaft in the middle, YES that is your vibration some people should learn how to do things right, not just do whatever they think might work good luck on the new engine purchase what are your plans for the frontend and brakes? hope you dont get discouraged with your project, there are some good guys here that will help you through the issues the last owner made for you. just ask and we will try to keep things moving for you Ron....

have a questions on set up of the steering system. I would prefer to find a good donor car/truck for the rack and steering colum but was wondering if any one had any advice. I removed the current steering colum from the car and want to start hunting down the other times. I am going to keep the 5 in drop with the disc brake set up that is currently on the car. Also question on the steering colum and the exhaust on the drivers side. what options do I have for the exhaust etc. I am still waiting on the engine so am unable to mock everything up to see what and how much room I have. I konw there wont bee much.

I have to admit that I have not done to much with tube axles in about 20 years, all the vehicles I have built have had independent front ends. so most of my knowledge on axles is pretty old, but having the rack mounted to the axle was a big no no. as the axle moves up and down the steering shaft would have to have some kind of movement or things will bind or break. I would look at the way the front springs are mounted to make sure that the axle is not moving around to much. I would go with something like a vega box and go with a cross steer setup like this:

That's a heckuva cool lookin coupe project! I would take a long hard look at the front end, unless you want to keep it badly for the LOOK, there are quite a few drawbacks... the rack with the straight front axle I've never seen to be honest. I love the shape of the car. Keep on posting, and welcome to MoParts!

I used the original straight axle, disc brake kit from Plydo. Mono leaf springs from Butch's Rod Shop. I also have rack and pinion but is not attached to the axle, the unit is from Unisteer. I had a bracket made to adapt to the Mopar frame. It still drives like a straight axle but I have no problems with the set up.

ron, just out of curiosity, have you ever seen one of these ? would it be possible to take a common M2 rack & remove the dr. side inner tyerod assembly then fab an extender[for lack of a better word] for the pass. side rod assembly ? of course the whole deal would have to have a custom mount fabbed.
no i haven't seen one in person but I had the same thoughts Ron...

Thinking out loud here. Why couldn't a guy take a Cavilere rack and mount it to the frame, then run the tie rod (for better lack of the correct term) from the center of the rack to the right side only then set the rest up like a standard cross steer setup? The center mount inner rod connections would make for a longer rod then a MII that comes out the end. A guy could set the rack more to the left side to better match up with the column and a longer right side "tie rod" ran to to reduce the bump steer even more. Wouldn't think it would make a difference to the rack if it only ran a tie rod to one side and nothing to the other side. Now, someone tell me how bad my mind is working tonight so I don't go out and do something stupid. Gene
