Thanks for the recommendation. I have looked at them pretty hard, but they are 1.5-2 hours away which I can do but it would make my world a lot easier to find some place local as I would have to tow the truck through Raliegh traffic, they all drive like it's the Coca Cola 600 on I-440 up there. If I lived closer to the Charlotte/Mooresville area, I am sure I would find lots of shops that do this type of work since that is NASCAR country. There are lots of old cars here because they take a long time to rust
and a mostly blue collar type economy when you get outside of Raliegh or Charlotte. I did find a local place that I am going to check out later today. They rebuilt my transmission a year ago and they said they do differentials when I called them yesterday. Thanks for the response.
