Well I have a 8.2 10 bolt right now with no posi. I want a 12 bolt with eaton posi. My motor with put out 450 hp. right now I am looking for a complete rear end to bolt right in. I was looking as moser and I like what I see but they dont have complete axles for novas, the closest to a nova that they have is a Camaro. I am wondering if it will fit. I have heard they are 2 inches wider, is this a fact and couldnt it be compensated with backspacing? anyone know of any new bolt in rear end built specifically for 3rd gen Novas?
