BorgWarner 9 bolt, 2.77 posi, aluminum calipers.
 

I'm selling the rear end out of my 89 Iroc.
Its a 9 bolt with 2.77 ratio gears, posi, and disc brakes.
The calipers are the aluminum PBR ones.
It comes complete with the full brake setup, ebrake cables, LCAs, and panhard.
The car has only 68k miles on it. I never drove the car so I cant verify condition, but vehicle was abandoned in 99, and not driven since.

I'm asking $200, (I will sell the brake setup seperate for $100)

exactly what was stock in my iroc, the 9 bolts are strong!
