The bump style are quite a bit newer. Not sure what year they changed. You can get the clips from
Carter\'s , but even if you attached the clips to your wheels, the caps would not fit flush to the wheel and would be hard to keep them on. I have seen the clips attached to 70's style ralley wheels to use the OEM caps. I'm going to attempt that on my '59 but haven't tried it yet. You could probably use caps for a 60's or 70's car or truck or a generic set of baby moons common on trailers if you want to stay with the wheels you have.
