Hi All, I saw this ad, I have no connection with the seller https://sfbay.craigslist.org/sby/pts/5793006332.html
505 Center caps do not have the mounting screw that you can see in the photos. On 505's the hex portion threads on to the rest of the cap which is bolted to the wheel. No counterbore around the center for the cap either. Might they be some older Speedlines or Compomotives? Image Unavailable, Please Login
No I don't think they are Compomotive. The cap look the same but not the wheel. They are very nice and and priced to be attractive.
