If your going to abuse that rear end you might want to buy some thick chromemoly tubes for it.
I've used Moser 8 3/4 and Dana 60 passenger car ends on several truck Dana 60 housings for my hot rods with no problems, all of them had 35 spline axle with the green bearings though I'm almost positive that they will accept the stock wheel bearings also, regardless of the axle size or axle diameter up to 35 spline Call Moser and ask them
They are a little more costly than some of the other cheaper ends that Summit sells, but they are more than good enough for what I've done
