WhiteDog, These appear to be the same hubcaps that I took from a 1970 Camaro and put them on my 1952 Chevy 1/2 ton pickup. I used 15 inch rims from a 1965 Chevy pickup and the hubcaps worked perfectly. I'm attaching a picture of my pickup with the rims and hubcaps on our pickup. If I didn't attach it properly and you are not able to open, I will be glad to send to your e-mail if you wish. Chuck 52
