This is one of the conversion kits to go from the pilot pushing to the pilot bearing, I don't believe that the slant had one from the factory, but I absolutely could be mistaken. Is this a better way to go?
The slant 6 had a bushing. The bearing I'm speaking about fits into the crankshaft register. It's personal preference. If you want to replace the bushing, just do that. Either way will work.
