i have a LS6 from a 2004 cts v. . the camaro braket will not work bec the spacing on the pulley are different. i bought a alternator braket from Dirty Dingo and relocated on the driverside top. . but if you have a stock corvette alternator braket that might work for you since its a top mount alternator and i dont see why you cant use your own alternator. . as long as the engine harness is the same it should fit. i think the camaro alternator only has one wire connecton. the LS6 has a two wire.
hope it helps.
