3rd gen brakes on a 4th gen rear
So as part of my LS1 swap my buddy is giving me his rear end out of his 2000 trans am m6. The catch is he had to take all brake components (caliper brakets and all) off to put on his 9" rear end. Will all 3rd gen components bolt right on to the 4th gen rear end?

Why do you want the 4th gen rear? What good is it without the brakes?

Probably for the torsen and 3.42 gears.
Sorry cant help with the brakes. The 4th gens have 4 bolt rectangular mounts for the brakes like the 1st and second gen's do.

Re: 3rd gen brakes on a 4th gen rear
4th gen / LS rear brakes are a simple bolt on the 3rd gen (excluding drum brakes and 9-bolt rears), so swapping brakes the other way should be a similar bolt on experience.
