I contacted one company, I think it was Speedway parts, and as a lot of suppliers say, that these smooth moon hubcaps won't work, but the secret to making them work is this: Because stock Ford fiesta steel wheels on have longer lug nuts (because the OEM lug nuts actually hold the hubcaps onto the wheel), they are longer. So by replacing all lug nuts on all wheels with the shortestlug nuts available, it eliminates extra long stock lug nut length normally standing up so tall that a aftermarket hubcap won't fit.
