Your '76 Monte Carlo will have the 8.5 corporate rear end. There is nothing wrong with that rear end if you build it right. I recommend a new 30 spline Eaton Pois and a set of Moser 30 spline axles. Moser axles are the only ones that will be a direct fit for the 30 spline upgrade. There are no 12 bolt rear ends that will fit that car. Just build your 8.5 correctly and it will hold up fine. Use the best quality parts that you can get, like name brand gears and a very good installation kit.
