SPECS ON PILOT BUSHING, CRANK PILOT HOLE ID AND INPUT SHAFT

Have it rebushed?

Pack it with grease, pound a bolt or closed fitting rod in to drive it back out, slam the new one in using a socket that won't get stuck in the hole, and get on with your life.

The factory bushing is oilite. The tolerances on such parts are virtually non-existent. Look it up by number and go.
Make sure you get the one for a factory stickshift crank if that is what you have. if not and you're adding the rowing machine, go with the bearing.

No crank machinist is ever needed for this unless you're converting. It is literally a ten minute job once the clutch is out.

The bushing will shrink considerably upon install. Let me know if you can't find them.
