Manual transmission swap
I just recently did a 4spd swap in my 68 Dart that originally came with a 904. Upside is you can reuse the same driveshaft since it’s the same length as an A833. The rest though, it was a challenge for me since it was my first time doing so.. I went off internet research on here, videos on YouTube, and my natural mechanical ability..
It was more expensive of course than just buying say a TCI trans that’ll drop right in but I wanted a 4spd. Where I live, there’s no resources that I’m aware of and I don’t know many mopar guys around here that would have a stash to buy from so I had to buy over the internet. I bought a 4spd setup from a shop that pulled it to convert it to an auto so it had the bell, trans, linkage, shifter, fork, flywheel, clutch, some of the pedal linkage.. I sourced the rest from Brewers. I had a buddy help me that knew nothing about these cars and it took about 2 weekends. Which wasn’t bad considering our experience level with the project at hand.
I lucked out and my crankshaft was drilled deep enough to accept the input shaft. I used the later roller bearing that goes into the crank register. I didn’t measure the ID to see if a bushing would work, I went straight to the bearing instead.
The pedals was the longest project of it all. I didn’t pull the column which would have made it easier. I didn’t pull the whole pedal assembly. You can remove the brake and replace it with the smaller pad one and add the clutch pedal to the exiting assembly. I spent the better part of 4hrs wrestling that since the quarters are so cramped. I hope I never have to 4spd swap another car again lol.. but if I do, I’ll have much better foundation of knowledge should that ever happen.
Best advice I can give is if your patient, can swing a wrench, and like a project… give it a shot, it’ll nickel and dime ya more than ya think.. overshoot your budget.. I did and I managed to cover it all. Now if I had some local buddies that were well versed in this plus a local source for parts, it would have been a little less of a pain.
