I just don't like hackin on the car unless I have to. I know, what he removed is probably miniscule.....never be missed. I would have marked the control arm, removed it, cut a "window" out of that front arm above where that bracket was it was hitting, flipped the "window" around backwards and welded it back in. That would make the control arm convex in that one area and would have cleared the bracket. Again, a LOT more in depth than cutting a small part off, but it would have worked and not compromised the integrity of that control arm.
