I bought an after market bumper and it's fine for an every day driver. I don't know who it came from. A guy bought it for a project he never built. As far as the bullets or bumper guards, I think they used the 57 for a pattern on the ones I have seen pictures of. I don't know any of the bumper guards in after market that are correct for 55-56. The door handles I have seen, the old locks fit in them, but you can tell they are reproductions if you look close.
