For sale is an 8.5" Grand National posi rear. The gears and posi unit are brand new. The gearing is 3.23. The rear has black POR15 on it and looks like it would be a good driver rear. A little work and it would make a nice show car. The only problem is one of the cover bolts is broken inside the hole but a drill and tap would fix that. Still seals without that bolt aswell. The rear is still very tight and It was going to be used in a circe track car until I traded the guy for it. He did weld spring holders on the perches but had the rear in my car and had no problems with it at all. Its a small pipe welded atop the spring mount so the spring cant come out (Pictures are the best description). Its literally a taller version of whats on the stock rear. It will not effect any functionality or performance at all. If you have any questions dont be afraid to PM me. I could use the room more then the rear. Will trade as well let me know what you have. If you would like pictures just let me know as well
