I bought some IROC-Z (3) centercaps from this guy on here, and 2 were in perfect shape, one with broken mounting tabs. Exactly as advertised, couldn't be happier.

I already have perfect centercaps, just with the IROC-Z button pried off of them, so I did some re-gluing and managed to make 3 perfect centercaps out of this deal! Just need one more now...

Thanks for amazingly fast shipping and prompt replies, as well as representing your product very well at more than reasonable prices. Thanks so much Kevinfirebird!
