Diff shop recommendation in Phx, AZ

[azsmokey]

I do a lot of things but I don't, or should I say have never build a front or rear differential. We are going through our 72 and want the 12 bolt and Dana 44 rebuilt. Can I get a recommendation for a shop in the Phoenix Metro area that can do a good job? I live in the north valley, in the vicinity of I-17 & Happy Valley. If there is a member that can do it, I would be happy to pay them instead!
