Complete 8.5" posi rear end for 73-77 Monte: ring gear has rust from sitting too long. Posi unit looks ok rust wise, but some dumbass attempted to weld the spiders. Carrier is not welded on, and can be saved with some different spider gears. Comes with extra housing and axles with 1/2" studs, and a 2.73 gear set and welded carrier.
