So I am going to skip some steps here as I was really pissed and frankly didn't stop to think to take some photos. Per the advice of Ddays and others, I built a little jig stand to hold the carrier and used my jacks to adjust it in place. Worked like a charm. However, like most, the damn bracket alignment put the stupid bolts right smack in the middle of the pinch seam.

Decided to try a different route to solve this.

Final product before breaking it all down and doing final paint.

What I can't show you is the 2.5 plus hours playing with those damn joints trying to get it to align. I think my driver lower is about 1/8" too high during install as no matter what I do it's a tight fit. Many thanks again to Ddays through both the corner and carrier install for taking my calls and texts to make sure I wasn't royally messing something up.
