OK, I started this post and I need some clarification on the codes. I have a 04A build 68 Z/28 and it's been stored for 40 years and somewhere along the line(during several moves) all I have is 1 'Upside down large DF non dated' wheel with the original tire still mounted...Can someone tell me if it's original to the car? When did the DF change to right side up, and the dating start? JM?
