help me see the difference

I'm looking at the precut masks for painting Magnum 500 wheels. Search shows these for Ford or Chrysler. I don't see a major difference. I know mine use chromed trim rings instead of being chromed at the wheel. They came off of a 67 Mustang. I don't know they were original equipment to that car. I guess I should look for logos on them.
