I have a 2000 Silverado with the 16" alloy rims. I've seen wheel center inserts that are flat brushed chrome look. They replace the original covers that have the lug nuts exposed. I don't want the ones with the GMC stuff on them that came on the Sierra's and the GMC Safari van. Did Chevy make some for their S-10 frame based mini van The Astro Van I think? I had a '96 Z-71 with 16" alloys on it that had the smooth caps, will these fit? Any help mucho appreciated.............Ward
