My Premier Diamond Lady is missing the top bolt for the coin door frame (1/4-20); it appears to be black powdercoat, and as well, it's a bit shorter than the others because of the bracket that swings there. How do I get a bolt that is done in such powdercoat? I have some black oxide bolts, but it seems that they should be powdercoat to go along with the door & frame. I suppose that this applies to any Premier of the era that has the same cabinet design.
