UCA adjustment plates damaged.

image.jpeg HELP!
Need some advice. The upper control arm adjustment plates on the body have been hammered flat. No idea why? So I was thinking.
1. If I hammer them back into position would they be strong enough?
2. Do replacements exist?
3. If so. Would the adjustment bolt locate the plates to be re-welded?
Or am I just screwed with a car that can not be aligned.
