I guess as you know the 76 has the thermal exhaust, that is very inefficient. Your muffler should be similar to the 78/79, and if so this would fit, allowing you to run a cat. If you still have the thermal style heat exchangers, and you add the cat, I would upgrade to the 86/87 heat exchanger which should give you a bit better performance, and hopefully the cat will allow you to remove the thermal's, if you have not already. Hope this helps....
