Well. I can't believe I read this whole thread. Sounded like a simple problem with plenty of help but it has ended up in the worst case scenario. So, my two cents worth. I've built lots of rear ends and restored plenty of housing. It is amazing how many housings are out there that are patched together because of bearing problems. Do not have it welded back together. Unless the shop has the proper jig AND knows how to weld it, it will not be straight. Get another housing pure and simple. Be sure and get one that has good axles because I would not trust that yours may be usable. Hopefully you can get one from a close source because shipping is expensive. I think you are correct that the 65 is a one year only housing and the most narrow b body. I've got one but the shipping you kill you from Texas to NY.
