These wheels don't really have a provision for moon caps, but I suppose clips could be added to them. There are holes for the original screws for the factory caps that one might be able to use to attach clips to. The caps I'm running are from a '94-'98 1/2 ton 4x4, the actually have the black plastic "nuts" that screw on over the lug nuts, just like the late model GMs do. It was really kind of a fluke, as I managed to find the special lugnuts I needed at a swap meet. Normally, those nuts are only available in 14mm thread, but I found a vendor that had them in 1/2-20 std. I'm not really certain of a source for those lug nuts, though.
