Pilot Bushing

That is what I have in the crank now, it was an auto motor out of 2000 3500van , the insert in your pic fits fine but I was informed that the pioneer bushing could be inserted to replace the bearing. So that is what I'm looking for is the bushing that will fit where the bearing is.
No such animal AFAIK, I suspect you were misinformed.
There's nothing wrong with the roller bearing, so I'm not really sure why you would want to revert to a bushing. The bearing I pictured is what was used by the factory...
