I have a 72 skylark with a 10 bolt . Pogo offers a position limited slip but Idk if its a full position...who sells um...I'm planning in getting 390s help please
If the rear in your car is original, it is an 8.5 10 bolt. Where can you get a Posi? Anywhere. Jegs, Sumitt, your neighborhood speed shop. I would contact Monzaz though. Bet he could give you the best deal.
