Doing a T56 swap in my '88 IROC, and the 2.77 rear simply has to go. Looking for a thirdgen 9 or 10 bolt, 3.42 or 3.45, or slightly higher.. preferably posi within a reasonable drive from Knoxville, Tennessee. I intend to pick it up myself.

Disc would be nice, but not absolutely necessary, but would like to find something that's good to simply install in my car...the T56 stuff has just about bankrupted me, so I'd rather not have to tear into whatever I buy.

 

 

I have one but I am in Texas.
No brakes. Have the backing plates just no calipers.

Texas would probably be a bit far...easy 3 day trip getting there an back, but thanks for thinking of me!

 

I had 2.73 gears in mine. I just bought a 3.73 gear to fit the carrier and had it installed.
Its a thicker gear to fit, but works great. This may be a option for you.
