Thanks for the posts so far. So Dr. Diff, is it still a locker? And as for the circle track question, it had a ring gear attached that was a 2.76 ratio, at least according to the numbers on the side of the ring gear. It also had the part number of 2070684 atamped on it. I tried to do a search, but came up with nothing. I am assuming by the part number that it is a Mopar part number. Not knowing much about circle track racing (ok, knowing absolutely nothing!!!), I wouldn't think that a 2.76 would be a good gearing for any racing application. If I'm wrong, please feel free to correct me!
