Plugging emblem holes in fenders

Great tip by Garry in AZ. I have been using copper back-up pieces on some of my patch welds, but wasn’t sure how to attach them to the quarter-panels from my donor car, which is from a Dart 270, hence the hole problem. Now I know how I’m going to do it. The magnets will do the trick. One of the reasons I’m doing the whole quarters on both sides is to minimize weld length and the amount of filler I’d need to use. I attached a picture of a test-fit of my left quarter panel, and you can see the holes I’m having to deal with.
