i have a disc brake rear out of a camaro, it is an open diff with 2.73, i had purchased the rear so i could put a spooled carrier and 3.73s in it but ended up seeing the other parts, so now im stuck with this one, you will need new rotors and new calipers, the old ones do come with it, the carrier has new bearings in it from previous owner, pics upon request, asking $100 or open to trades, email for faster respose otecnick@yahoo.com, thanks
