That is actually the dealer order confirmation number. It is not possible to determine the number based on a cars' build configuration. When the reproduction body tag was ordered they simply used the next highest number. I recall being asked about it when the car went into restoration; I may have advised they do that.

Odd ZL-1 fact: the lowest body number is Berger ZL-1 #3 #211785. A Berger L72 COPO is #211786.

Had two lengthy phone conversations with Jerry Huffman a few years ago. They were a high-performance dealership in Farmington, IL. For years we have thought it was a wonderful coincidence that Chevy built 69 1969 ZL-1 Camaros but it was not. Jerry told me Central Office contacted their dealership to see if they were interested in ordering a ZL-1 Camaro. They had decided to end the program at 69 units and needed to build 17 additional cars, possibly to consume engine production. So, they [foolishly] ordered two cars [#66 & #67] without knowing the option MSRP. The cars were a headache for the dealership; that's a story for another day.

Last ZL-1 was built June 3, 1969.
