It's not easy to even find a chrome shop anymore, as most have been sadly regulated out of business.

That paint really is shot, so I agree with caveman, do what feels good. If you can, try and take some pictures of what's left of the decals and maybe somebody can make them up for you. It might not be worth what your going to put into it, but that's not always the most important thing, some times it's the satisfaction of keeping a little piece of history alive....
