If you are talking about those little spring-steel wire clips specially made for the '55 trim piece that go around the parking light housing, it would surprise me to no end if any body shop had them. Those clips are a one-off. The hood nose trim clips, although the same width as the fender clips are completely different from the fender clips due to the rectangular holes in the front of the hood for them. I think you can still get those from the Repro parts suppliers, but they have never offered the fender clips to my knowledge.
I made mine out of little square pieces of spring-steel cut out from a strip, drilled holes in them and put a short machine screw in the hole. It's difficult to get behind and put on the washer and nut, but it is doable.
