My question really should have been are the wheel bearings for the 8-lug drums and the 10-lug rotors the same? If so, then I would assume they could be swapped. As for the fronts, I'm hoping I can use the beam front axle from a late-90s Chevy 3500HD, which also has a 16,000 GVW and 10-lug rotors. (That vintage 3500HD is the 88-98 body style truck.) On the GAWR, I'm a structures engineer (plus it'll be my butt in the truck), so I don't want to be guessing.
