I had the issue just a few weeks ago when I noticed one of my rear wheels had a crack in one of the spokes. My '03 ZO6 has only 10,305 miles on it and sits in a heated garage and now this happens. Anyway I researched and found a place that sells used and believe it or not NOS C5 wheel. I purchased a "NEW" rear wheel and it arrived this past Friday. Yes it is brand new and not reconditioned as some people may think. Contact Mike Figlak at [email protected]
