I agree with the others. I don't think I would worry too much but I like what Claudemiro said about posting a picture. These weren't precision made car anyway. A lot of people forget as you add caster the cross section of the control arm becomes oval as it goes through the body hole.
I learned a tip from a Hungarian machinist I used to work with. When he had to drill a hole through sheetmetal he would use a small piece of cloth over the spot to be drilled. I asked him why he did it. He said it helps keep the hole round. I've done it and it does help.
I'm not a complete idiot, pieces are missing.
