Pilot Bushing

No such animal AFAIK.
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...
Yes sir it is what the factory used and this is just a perdonal preference for me I've always used bushings without a single failure and with out fear of tweeking that edge of that needle bearing. I'm sure the factory had there reasons for the change to bearings but it wasn't because of prior bushing failure , more thsn likely it was assembly line cost but I'm happy with bushings I'll be long gone by the time it wears iut lol
