I'm still trying to find the year of this Bolen Tractor. Are there numbers on the frame? I found numbers on the engine model=JRA-10d Serial 49390014 and stock? 292928. I need a right rear axle shaft and the inner sleeve in the wheel hub that has a key way. Where can i find them? I didn't see any parts in the listing. I would like the owners operating manuel and the trans differ. manual (6 speed) for repairs.
