Does anyone know what rear end chevy used in the 83-88 Monte SS? Posi? Gear Ratio? Got one thats bad and would like to find another from the junk yard instead of having this one rebuilt. Surely they are not the same as the non-SS montes? Would any of the Camaro rears be the same?

the monte uses a 7.5 rear posi was an option even for the ss, ratio I'm not sure of probably 308 or 323 this size rear came in everything from 82 up,T/As ,Z/28s, IROCs Monte SS, ect even caddy fleetwoods.You can get one from the boneyard and look for the limited slip tag for posi.If you can't find one e mail me I may be able to help

They used a 7.5 inch 10 bolt. Any rear from a 1978-1988 G-body will work. I think you could get 3.42 gears in some of them. This also includes the El Camino's and the El Camino SS from 1978-1987.
