If it helps... Harbor Freight sells rubber-insulated clips that are stainless-steel, and come in varying interior diameters, that you can use instead of the old clips. They're realistically better than what was stock, and unless you're going for a concourse restore, this is what I'd recommend.
Amazon has them too:

You can get an entire kit in a plastic container, sorted by size, for half the price of a 10-pack. But just wanted to send that link because it was taking me too long to find it online at Harbor Freight's website.
