yes i kno its becoming popular with the G body guys since a 12 Bolt 8.5 Gm came in Cutlass 442's and Turbo buicks. and by them becoming more and more rare its putting the price on these rear ends into a heavy price as a trashed needing rebuild will cost 800$ for the rear and a mint one or rebuilt will fetch 1500$+ i picked my rear up for a 6pk as it was a leftover from a car build and i snatched it up. i am upgrading the front brakes on my car so i figured go all out and do rear disc too. so as i rebuild it with new seals and 3.73 gears. will the MKVII disc's work?
