I have a complete 7.5 rear end out of a 88 gta. It is in great working order and the posi unit works great. It also has disk brakes. I haven't pulled it out of the car yet but it at least has 3:42 maybe 3:73 gears. I would take 350.00 for the complete rear end ready to bolt in. Also I have a 700r from the same car. It is also in great working order and shifts well. I will take 250.00 for it. these items would be for pickup only and I live in ky. Would consider drivin small distance to meet.
