people "pm me with questions". Miles I have no clue, bought it off a person with a 383 lt-1. Had no problems, and has no problems. Was going to put it on my Iroc but ended up buying a strange rear for my LS1SS. So the moser from the SS is going onto the Iroc. Dyno Don took it all apart to install the ls1 backing plates. Nothing wrong with the posi unit, axles, or anything on the rear. thanks
