After revewing your pictures...
I don't know enough about your, newer, non Advanced Design, truck to say if it is a 3/4 or 1 ton. Perhaps 1 ton?
I see that you will want to keep the wheels you have with the dual rears.
Assuming they fit the Dana 60 you found you are all set. If not then I would look for a 60 or 70 that has 8 lugs and came stock with dual wheels.
After thinking about it, I think you will be find using duals on what was a single axle. forget what I said earlier about the bearings and there placement, the load is sitll placed in the same relationship to them either single or dual. Anyone think otherwise, and why??
