I've got a 63 impala that I've taken the engine and trans out and swapped them for a somewhat peppy 350 and a 700r4. So far I've broke two carrier bearings. Only takes me about 6 months to break one. I think the problem lies in the angel of the front u joint. Anyone have any other thoughts on this or possibly a fix would be great. Also, would it be possible to put a one piece driveshaft in without having to cut up the car?
