Dropped spindles roter question

I believe you need rotors for 84 to 87 g body, the safe bet would be to use them for an 87 g body. The early cars had a smaller spindle stub and somewhere between 80 to 83 they changed twice I believe. Below is from this thread;

My on-line g-body research told me we share the same front suspension from the control arms out (except spring rate) as an S-10 truck. Knowing this I ordered a set of S-10 hubs made from cut down rotors from a guy on an S10 forum. They came with new seals and new extended studs, $110 shipped. Being under time constraints this was quicker and less stressful than trying to find a machine shop that could cut down mine. After hacking up my 79 spindles to fit the LS1 caliper adapter bracket and painting them and the S10 hubs, I found out I just flushed $110 down the toilet when I tried to assemble everything. My 79 g-body outer bearings were too big for the S10 hubs. A trip to the auto parts store later revealed the S10 outer bearings were too small for my spindle. At this point I was getting a bit frustrated.
After a big fail with the hubs I did a little more digging. All listings for interchangeable parts, a drop spindle for example, list S10 and 1982+ g-body as the same part numbers, but no one could explain to me why that didn't include the 78-81 cars. Further digging revealed the deal-
All 1973-1988 A/G body cars and non-sealed hub S10s have the same inner front bearing and seal, part # 6 for the bearing.
All 1973-1978 A/G body cars have the same outer bearing and spindle pin measurements, making the 1978 g-bodies, which are actually still called A bodies, the original bast@rd child. This bearing has a smaller inner dia than the 79-81 cars, bearing part #2.
All 1979-81 g-body cars have the same outer bearings, larger outer and inner diameters than the 1978 g-body and S10s, i.e. a larger spindle pin. The rotors for these cars also have larger hub diameters. This makes these cars the step bast@rd child. Outer bearing part #3. A 1978 or an 82+ rotor will not fit a 79-81 spindle. How dumb is that?!
All 1982 and up g-bodies and S10s have the same outer bearings, using a smaller outer and inner bearing diameter, i.e. a smaller pin. Outer bearing part # 34. Everything seems to swap between these two vehicles.
