Square up my rear post salvage
 

Hi everyone, I purchased a salvaged 04 C5 Targa Top 40k Miles 6 speed. The body work was completed and all is well but the rear is not squared up. The previous owners body man said in order to get it back to factory it would need an adjustable Upper control arm. I wasn’t confident I would get any truth out of him after he told me the difference of each side was only 1/8 of an inch. In the pics, clearly the gap is much larger between each side. I knew I what I was buying. Just wanted to hear of anyone’s experience with a situation like this of what correction can be made by an adjustable upper control arm.

That could be a caster adjustment.
But, body work?

So, I guess you have to confirm the frame is true first.
Onto a measuring rack would be a first step.
If square, find a good four wheel alignment shop, and then look for bent suspension.
If all okay, then again I'll say it is a caster adjustment.

In my area, frame measure about $400.
Alignment about $200.

All FWIW. Good luck.
