What do I need to swap the perfect engine/tranny out of a 9C1 Caprice thats been rearended by, it looks like an 18-wheeler....! The engine and tranny are untouched, as the driveshaft broke off the axle when the vehicle collided. I have a 1982 LU5/200C(CeaseFire) with t-tops. Would that be an issue of should I just rebuild the LU5?
