I am trying to find 12" wheels (4 bolt holes) that will accept a baby moon cap. I have been able to find caps to fit, but no 12" wheels that accept a cap. All I can seem to find are the white painted wagon wheels. I currenlty have 8" wheels with the 3 protruding dimples. I am told these will accept caps but I really want the taller profile of the 12" wheel. I would even go with a 13" if I could find a 4 holer with no offset. If anyone has any leads, that would be great!
