Yes the '88-'98 6 lug rotors do use the same bearings, and they do technically fit the '71-'87 spindles, but they don't line up with the calipers. So yes if you want to use those rotors, you will have to use the '88-'98 1500 or LD 2500 spindles and related parts. This also requires you to change the LCA to a C20 LCA.
Otherwise, if you're going to use the '71-'87 spindles, you will have to buy the aftermarket 6 lug rotors as Russ65C10 stated.

When I tried a parts lookup, it appears that the bearings are the same, A3 and A5, but is that enough to insure that the rotors will swap?
