Are you aware that there are different pilot bushings depending on whether the crank was an original stick crank or not? NAPA sells the proper one for an unfinished crank. Trying to put a standard one in an unfinished crank will crush it. Go ahead, ask me how I know that.

The roller bearing is from a Dakota truck if you want to try that route. It fits in the register for the torque converter, so it doesn't matter if the crank is finished or not.

IF the crank is unfinished you will have to trim the end of the pilot off. That's a lot easier than trying to drill the crank with the motor in the car.
