I had to mess with shimming and i'm now at just under a 1/2" difference side to side and i'm done messing with it. I don't know what it is but these cars just have a damn lean.

The frames twist along the length, that's where the lean comes from on some. And that is what the brace is supposed to combat, that longitudal twist. Once the body takes a set, on a 'leaned' frame, you have to straighten both. If not, once you bolt the body back up to the frame the body will just pull the frame back to where it was.

Jack up the car on the frame on the front side of the side that leans and leave it for a couple weeks. Do that a couple times and the lean will be gone. You could even loosen the body bushings while it's jacked up, then tighten after the couple weeks when you let it down. Could help hold it from tweaking again.

Careful though, you could impact panel alignment, have to watch as you jack it up.
