Have an 85 shevy 1/2 ton 4x4 with 10 bolt 3.08 pumpkin and stock locking hubs.. ALso have a 90 1.2 ton surburban with a 10 bolt that I spent $2,000 on (stupid, I know) with hardened axles, Eaton posi, 3.73 Zooms, etc. The front has Warn hubs too. Id like to swap the 90 pumpkins straight across with the 85s. I want to scrap the 90 and keep the 85. Are they exact bolt on?

Also, the 90 suburbans engine and tranny has only 60,000 easy miles. I want to buy a high mile suburban from 1993 to 1997 and put my low mile engine in it. I cant get really nice mid 90s suburbans here for under $2,000 that have mega miles on them. Will my 90 injected 350 and 700r trans go into the newer subs? Thanks.
