The spare wheel in my 05E '69 Z, inside a never-been-on-the-ground Sport Car 200 tire (which doesn't really prove much), has rim stamping code that is clearly "K-1-8 7 24 FW", although the "W" looks much like an upside down "M". From older posts, I gather the "FW" code wheel is a '71 and later Chevelle & Monte Carlo wheel. If this is true, how do we explain a July 24, 1968 date with an "FW" code? Having spent 30+ years working for that other "C" car company and crawling all through their many assembly plants, I know first hand that almost anything is possible with parts being flown/trucked all over the country in emergency part shortage situations. But it doesn't explain the 1968 date code on an FW wheel. I'm confused! The photos I have of the tire and wheel were too large to include in the post but I can attach them to an email if anyone would like to see them. Thanks.
