I have a stock rear from a newer style camaro that will fit in any camaro/firebird 1982 and newer. This came from a V6 car with drum brakes I know its not posi and dont know what gear ratio it is. All my research show that these rears have the 28 spline axles The rear is complete drum to drum $200.00 for the rear.
I also have a stock posi unit with richmond 3.73 gears I will only sell with the rear for a extra $100.00. This rear has 28 spline axles where the third gens have 26 splines.it is also wider than a stock third gen rear. so you can run a bigger tire. for local pick up. will meet someone 100 miles from my place for gas money located in california MD
