If you had the town you live in listed instead of USA, someone close to you may have something to help you. When I see a member looking for a part and their location is close to mine, I try to help out.
I may have a 2.94 axle but it is in a '76 model car with the bigger bolt pattern.
too bad you're in CA, as I'd be all over that for my duster since I just did a factory disc conversion on my drum car and need to change the rear bolt pattern on my car, but I'm in west Michigan.
