Lower control arm sway bar tabs not the same height

My guess is that they're different as I know for a fact that they aren't bent as I've owned the car since day one. Probably just the way they tabs were stamped out and shaped back in the day and then welded on by hand and close was good enough. I guess I won't try to reinvent the wheel and leave it alone and call it good enough. But it does make you think about who was doing the final inspections back in the day as to what passed and what didn't.
