89 C3500 with stock steel 16" wheels. Looking for a set of center caps, or at least 2 of them. Only had 2 on it when I bought the truck. Mine are the ones where the lug nut covers don't spin or remove. I think the ones that has the removable lug covers would work as long as it's the center cap that just pops into place and not the kind that is held on by the lug covers screwing onto the lug nuts
