Borg warner 9 bolt rear end out of a 88 Formula Firebird. It is a posi 3.27 gear. Has the later style better disc brakes with the aluminum calipers and Raybestos ceramic pads. Ebrake cables included and Ebrakes do work well, car is a stick so I used it. Braided brakes hoses at calipers. Has less then 10k on a full rebuild. Was coated with POR-15 at that time also. Has weld on lower control arm relocation brackets. Only issue is last couple winters when car sat in garage the pinion seal would leak a little. Nothing crazy though would just leave spot on floor. Asking 400 or make offer. Located in Topeka Kansas.
