All of my YA wheels are 14X7. I don't believe that you will find them in any other size. You might find the same style wheel in Olds or Buick in 6" but it will have a different code. Ford, AMC, and Chrysler used the same style wheel with a different bolt circle. Then again, maybe I'm about to learn something new.
