Could someone let me know if a center console automatic can be changed over to a five-speed manual transmission w/o altering the floor pan hump too much? I'd like to keep the original 727 and have it available to put back in the car if I ever sell it and the new owner wants to change it back to auto. My car still retains its original 340 motor. I assume that the pedal assembly would be bolt-in. Any information, good or bad, would be greatly appreciated. Thanks.

Surprised at the amount of answers.
I am just starting to install some of the parts of the Keisler kit.
Would like to here some feed back on the install as well.

Floor - 1

I cut it out very carefully and could be returned to stock fairly easily. The install overall was pretty straightforward and I am very happy with the results. I did the TKO-600 from Keisler with the Hyd. clutch kit and installed it in my 69 Coronet R/T vert which was previously an auto/console.

You can see at the far left side the small zinc plate on the firewall. This is the inside of where the clutch master cylinder mounts.

Of these pics, the one that is missing is how I patched the floor after the trans was in there. I used the Keisler sheetmetal, as provided in the kit. I bent it to the shape I needed, and wrapped it top and bottom in this heavy roofing material from Home Depot. It comes in a roll and is about 8" wide, very sticky black tar on one side and metallic layer on the other side. This is great for heat/sound deadening. I covered the sheetmetal piece with this stuff, and it is in there with sheetmetal screws currently. If I ever tear down the car for proper paint/body, I will put it in there better, but for now it seals just fine and the car is noisy anyway because it is a convertible. I'll try to get pics of that part soon, but I will have to pull the passenger seat and console to get to it.

Bad news!....you'll have to put in a 4spd hump,and buy a new carpet and I fully recommend cutting any part of the floor that interferes with attaining a proper driveline angle, the Keisler E body shifter will "appear" were a factory 4 spd pistol grip would,.....I'd recommend, cutting the floor, hold off welding the 4 spd hump in, install the tranny and shifter,phase the driveline, you don't need a drive shaft for that, but you do need an inclination degree wheel.....begin by mesuring your rear pinion angle with the car on the ground, fully equipped as if you were going to drive it, then measure the transmisson, and adjust/ shim/ modify/ whatever to phase your driveline,or rear end.....then install the hump, based on shifter location (centered in hole), tack into place, seam seal, finish install

Darren.....Bad News dude!,....I'd get rid of that "tar adhesive" stuff, and just pad with the 1/4 " thick heat barrier from summit,....because the Tremec's aluminum case, esp when in OD gives off some HEAT!!!!!!......I could fry an egg in my console in my Tona" when I cruising the highway......that tar base adhjesive will start stinkin, and becoming gooey.......just tellin ya now!

I just did the keisler conversion in my 70 challenger. I replaced the auto tunnel with the correct 4 speed one. After this was complete I sitll had clearance issues. The kit came with an extra piece of flat sheet metal and a template to use it if you still had problems, and of course I did. Also,I've heard the ebody's have greater clearance issues. So after all this was done it was a fairly big mod. Oh and the pedals are the easiest part of the conversion! Just lube up the bolt with some wd-40 a few days before you do the pedals.

Cool replies, I tried asking about this earlier in another post, but when installing the clutch pedal and the hydraulic master, I can't seem to get the rod in a good location.
Should the pedal be up against the rubber stop when hooking up the push rod? if so then the rod is too short.
Then if I put it in the hole closer to the push rod, I can't get the rod short enough and it is on an angle.
Any ideas?

I just went out and snapped this pic for you... it isn't very good but maybe gives you an idea. I have mine to where the brake and clutch pedal sit at pretty much the same height, not sure if it is supposed to be that way or not. The angle is hard to see but I would guess the top of the pedal is about 1.5" from the pedal stop. I did see Shafi's post that it should be all the way up to the stop, but mine seems to be working fine as-is and I have the proper travel at the master cylinder.

I need to clean it up a bit under there, maybe I can get the car out in the driveway tomorrow for a better pic, I took this laying across the seat and console and upside down.

Again this is a 69 Coronet so your E-Body might be different.

Thank you very much for your time.
I hope the pic comes thru.
If I hook the push rod up to the correct hole it sits about 1.5" to 2 " away from the bump stop as you say yours is.
Thanks again.

That's the hole I am using, and I am 1.75" away from rubber stop.
You are supposed to put the spacer on the other side of the pedal so your push rod is straighter.
Thanks for the picture I am going to work with it in that hole.
I asked Jeff at Keisler, but he wasn't sure and said that a tech would contact me with the info.
I haven't herd back from him yet.

I'll try and measure and get a better pic this afternoon. With my spacer on the other side the rod hits my brake switch housing, and the rod is actually pretty straight the way I have it. I think the best solution would be to cut that spacer in half and put half on each side, that would work in my case.

We have several different lengths available for the push rods. Give me a call and we can have you take an easy measurement so we can send out a longer rod for the master.

I wouldn't necessarily use the words "bad news". In the event you wanted to put in a 4spd you would have to install the 4spd hump. In some instances you will have another piece of sheet metal for the right side of the tunnel. This comes in most cases when guys are working out the driveline angles.

When finished the car will appear stock looking and the shifter will come out in the correct location in the center of the 4sp console.
