A 4spd shifter from different cars can have different offsets and different placement from front to rear. If you can get a shifter from a first gen. all you have to do in cut the right size hole in the tunnel. I think 2nd gens are probably the same as well. Other shifters may require some mods. The cross member for a 350 and 4spd are the same and driveshaft length is the same as well so there is no problem there. Like Larry said, a donor car makes the whole process a lot easier.
