found my first Z28

[92646]

I am not questioning if the trim tag is real but that is earliest X33 I have seen. In the past I have seen 12C being the earliest. I just learned something new.

12B is ok for X codes, definitely the earliest they started. The rear spoiler looks properly painted, check for the different diameter torsion bars in the trunk for the decklid (spoiler equipped cars). The motor if it exists would most likely have the vin on the front pad for an early Dec. assembly.
