Not much as far as putting the tranny back in. I got a dummy shaft from the auto parts store to get the clutch centered. I had some head scratching on the rest of the pedal and such but only because I had gone to an engine for a '56 chevy. My next one i am going with the original engine--no need to modify. The universal is ligical once you see it--might need a gasket for the ball and socket joint(or whatever it is called) But I used silicone.
