I agree and now looking at it... now I don't think it's gonna be too easy to make those unique cap clips like you said. They appear to be flat spring steel. Probably be pointless to have a machinist try to duplicate them because it's likely they'll break installing them onto the caps. Hmm... any ideas? I know this is a super small detail item that you really..and I mean really, gotta look to find, but it would be cool to have them available to put back on our cars if going that far on a restoration. As for now, I can't even say for certain that all cars had them.
