WOW. Thanks for the info. I will keep looking for YH wheels with an earlier date.
Mark, did you mean to say your car was built 04C (instead of 04L)?
Kurt, please clarify, my Z was completed on 04/22 - 04/23 (04/21 is the first day of the 3rd week)?
So the assemble process is like this? From a CRG article, it took two days to get through the Fisher Plant and 1.5 days to get through the GM Plant. If the cowl tag was attached on day two (04/22) at the Fisher plant, that would mean that my car was started on 04/21 (04/21 is the first day of the 3rd week), cowl tag installed on 04/22, wheels installed on 04/23, and car completed on 4/23 or 04/24.
It took 7 days from the wheel stamp date, it sounds like the latest wheel date would be 4/15 (4/22 - 7 days), correct?
