That's the Eaton guy there.
As for bearings, None are interchangeable. I tried. Only bearing I have not checked on yet is the pinion support bearing.
Stay tuned. If I can find someone to machine my 14 Bolt hubs for cheap (free) I will show you what I have to do to run the 14 Bolt parts on my Eaton.
Edit: don't forget about the mythical 3.92 ratio discontinued aftermarket offering.
