I bought this disc posi rear end a few years back for my project, not knowing the one on the car was a posi already. I got this from an old man who parted out his 1988 Trans Am. When I bought it from him, he opened up the rear cover and showed me the inner gears etc. I forgot what he said the gears were, 3.23? Or 3.42's? It's been stored in my garage since I acquired it. I've had it since and don't need it. I don't want to ship this. $250
