The trim tag was issued by Fisher Body when Chevrolet scheduled the unit for production. Even though the Gibb ZL1s were ordered on the same day, they couldn't be immediately scheduled due to material availability. In the end, 2 had 12E tags, 36 had 02D tags, 4 had 03B tags, 8 had 03D tags. The first two built were 222002 and 222003, also the only ones with sequential VINs. 222001 was the 14th built. All of the 02D tags were built March 4-12. VINs were assigned in sequence as bodies were received from Fisher. Cars were not built in VIN order.
None of the Gibb cars was the first ZL1 ordered. #3 was the first ordered, bearing body number 211785. Gibb had friends in high places.
Dealer orders were not allowed to linger. By the end of July, 200,281 69s had been built but over 277,000 orders had been logged. Orders were typically cancelled because of capacity/allocation but errors and equipment changes were also factors.
