I have finally got my 383 th400 set in my camaro yesterday, and it looks sweet. I knew the 700r4 trans was longer than th400 making my driveshaft 2" short. Ok I have a yoke from 4l80e that is 6" long verses the standard 4" that come with the th400, and 700r4. Would that work? Or how for does the yoke have to go into tranny and how for can it stick out? Just a thought that would make it easier? :idea:
