This is bad.

^ x2 i have seen this first hand. I got a used housing from a member on here. (Clintag) that upon re assembling the rear figured out the dr side tube was tweeked about 1/8 inch out! Had to have flanges cut off & new ones welded back on with alingement bushings & bar through an empty center to square it up. Is this a (new to you) rearend at all?
