Help identifying problem

Hello everyone, I recently did a little spin in my z then came to a rest (hella sweet parallel park) against a concrete curb with my driver side rear wheel. I broke the wheel, broke one control arm and bent another. After I found a replacement wheel and control arms it was all put back together and the rear alignment is still off by about .5" (don't know exact alignment specs the wheel just isn't sitting straight, but is drivable.) The collision guy said that there must be another part that is slightly bent but under a visual inspection it is unclear which one. His solution was to buy new parts one by one until the bent part is found. Does anyone have any idea which suspension part would be a plausible culprit? Any help is greatly appreciated. As it stands now I think I am going to order a new hub and see if that fixes things.
