Trim rings, not positive because the I have never found a paper sticker with the p/n on it that I could read. I'm only guessing that as long as it is a 6 inch rim on a 70-73Mustang, Cougar, Torino or Maverick I think they are the same. Somebody might have more info on the rim with but it seems like the 351 and smaller engines got a 6 inch and maybe the 428 or handling packages got the 7 inch.
The hubcap is a C8O p/n which is stenciled on the inside of the cap.
