I live in Phoenix AZ, and I'm looking for someone that can install and set up a new set of gears in my RC. I was going to get a set of 3.90's. I have a dana 44 front, and a 9 1/4 rear. I know that I have to get a new section for the 44(I have 3.23 now) to go with the 3.90. Doe's anyone know anyone that KNOWS how to set up a MOPAR rearend?? I had Desert Rat set up whats in there now, and they did a really crappy job. I don't think that the guy didn't even know how to set a mopar rear. I read up on the "how to " section, and I think I can do the rear end with out any trouble. But, the front end is a different story. I don't have the case spreader, etc, etc. So, if any mopar maniacs know how, Please help.
