None of the 50 cars ordered by Fred Gibb Chevrolet were ordered or built with D80. A few have been retrofitted.
At least 12 of the other 19 ZL-1s were built with D80. In some cases, original paperwork exists for verification. #61 has retrofitted D80. #69 has its original D80 body tag.
#3 was built [3/4/69] with D80 and the 1st design [59”] rear spoiler. 17 of the other 19 ZL-1s were built after the 2nd design [61.5"] was completely implemented.
