I got into a crash a while back and I found I somehow banged up my rear seat stay. I spreaded the seat stay but I dont think I spread them the right angle. Meaning my seat stays are different angles from one another. So now my wheel is a little angled off center. What to do? Should I try bending the seat stays again to make corrections? Or would just tightening the track nuts in the right place of the horizontal dropouts be enough to make it angled straight.

THis is just like 1 mm angled off from center. It does show since one side of my tire tread is more worn than the other side.
