8 1/4 rear

The bearing is in the housing on 8 1/4's and not on the axle like 8 3/4 and Dana's

You can kinda say that, yes. But the bearings do ride on the axle, similar to the GM style. They are not however, the tapered roller style like the 8 3/4, which is what I meant.......they are much closer in design to the green bearings than the tapered roller.
