Re: Need compatability info on a Manual Transmissi
You can pretty much put any tranny in your car from 70-83 in it.
When I got my 76' 2+2, it had a 4-speed from a 72 in it. After I blew that one, I got a B/W 5-speed from an 83' Turbo. The only thing you will probably have to change is the driveline, and maybe make the hole in the floor for the shifter bigger (not sure on the last one as I have heard both ways and I didn't have to do anything to mine)
If you want a direct replacement for the 5-speed you have in there (no modification whatsoever to the existing parts), any 5-speed from a 76-78 should bolt right up. (not sure about 79-82 though)
