Can I cut here? (QA1 upper control arm issue)

I would have fixed that a different way and not cut the CAR, but you got it done and that's all that counts.

Usually, I agree with this. I go to pretty great lengths to only modify my car in ways that could be put back to stock if I decide to go that way 20 years from now. In this case, it was a tiny piece of sheet metal to trim. There’s no way to safely modify the control arm itself...
