Second question. With my car body off the frame and soon to be sent to the blaster I'm looking at the ease of taking the rear end off there and getting it checked out. I looks like it hasn't been touched since 1966 and could probably be gone through. But of course rear ends are super expensive to mess with. I also come from the school of thought, "if it ain't broke don't fix it." But I haven't even driven the car so I don't even know if it has problems or not. If you all were in my shoes what would you do? Have a rear end shop look at it? Or put a completely different rear end under the car? It's a 66 lemans convertible with a 3.23 so I assume it's a 10 bolt? Did these do alright in the cars for everyday type stuff? Posi would be nice but I'm probably getting greedy there. Unless of course it was an easy swap.
