Bought a bushing for an auto trans and it pressed in correctly - fortunately the bushing ID was the same for both trans shafts.

These things do get mixed up, even by the manufacturer. If the pilot bushing is at all sloppy in the flywheel, could be the problem.
Correct me if I am wrong, but automatics use flex plates with torque converters, not flywheels...at least not one that could be used with a clutch.

Generally replacing the pilot bushing is a standard procedure when you replace the clutch. I know from experience if one is bad the other will go out shortly after. You also want to consider the replacement clutch depth and your throwout bearing collar. With Datsuns there are a couple of different sizes....I am new to Chevys, but that could be something to consider. Like it was mentioned before, if the bearing is spinning all the time it will overheat and go bad quick.
