The engine you are installing (62 impala engine), what transmission did it have? Was it an automatic? If so did you install a pilot bushing in the flywheel for the front of the transmission shaft to be supported in?

I have two questions. #1. Is the pilot bearing in the flywheel or the crankshaft? #2. Did the OP have any problems finding a pilot bearing that fit, given that the engine came from an automatic?
