Everyone, i have a 1971 ss. It looks like i have 4 fw code rims with the correct dates. my question is does anyone know if there is supposed to be a fifth rim that same size. I had heard that it would have been a rally but it would have been a 15x6 not a 15x7. Also the documentation im my reading says the ss optioned car would have xy codes. These are all fw with the spare missing.
