The 258's T5 uses a pilot bushing, I think the 304 also uses one. The ID code for the 304 should be on a plate on the passenger side valve cover. If there are two cranks, I would just buy both bushings or bearings and return one.
There also should be an oil wick in behind the pilot bushing that needs to be pulled out and re-oiled.
