Hi Giorgio, I see that you have a set of center caps for those 5 point wheels that kevin shows. I can sure use them along with the retaining clips. New is good, but hopefully they aren't super expensive; I would be fine with used ones also. My direct email is: stobias@att.net
As far as the lug nuts are concerned, I have a feeling that my old ones from the steelies will work fine. Thanks, Steve
