Re: best place to find 3.73 posi rearend
Some of the 4th gens had it with disc brakes. I have a 91 z28 vert that the previous owner put one in. It's pretty much a direct bolt in, the parking brake cables are different though between a 3rd and 4th gen. The only thing that will happen if you get one is the rear end on a 4th gen is about 2 inches wider, so each tire will stick about bout an inch or so more than a stock 3rd gen rear. On my car, it puts the outer edge of the tire pretty much right in line with the outer edge of the quarter panel. I like it, it isn't bad.
