There are dimensions for the B01 and B52 wheel bearings in the Photobucket link in my signature (see bearing folder in the trucks folder). Pretty sure the outer WB can be replaced with a tapered roller from a late 70's Camaro. That's why the 5 lug conversion only needs a sleeve for the inner bearing.
The inner bearing is the tough one and MBS makes their 909052R, but good luck trying to buy one outside of a set from the suppliers.
