Sheesh. Every week somebody wants to put a 7 1/2-7 5/8" ring gear POS in their truck. NO NO NO NO NO NO NO NO NO (Is that enough Nos?) Anybody who runs the Camaro/Firebird hard ends up replacing the rear with something else. If a Camaro rear was suitable for a truck, GM would put it there already. If you want a late model rear to swap into your truck and you want disc brakes, get a 6 lugger from a 2000-2002 or if you've got 5 lug, go for the Impala SS 8.5" 10 bolt which gm DID put in a truck. Another option for six luggers is a light duty 3/4 ton semi-floater 14 bolt on some 3/4 tons from 88~96. Even better for 2 wheel drive trucks, just build your 12 bolt. You've already got it and can get a disc brake setup for $400 like BobbyK. Camaro rear is too narrow, too thin axle tube, not enough ability to shed heat from the brakes, designed for a lighter car with different weight distribution, etc. etc. etc.
