Default Need some help.

Ok so I need to get a new rear. But I'm not buying a 12 bolt or 9in. I want to get the Detroit truetrac but I don't know what part number I need. It will be factory axles. So If I can get some info on where would be the best place to get these items that would be helpful.

Mine came with a Detroit Trutrac upon purchase. I can ask the previous owner where he got it

You need one for a 28 spline 7.5, this should be the part # 912A317. Im sure one of the sponsors sells it.
