Nope.
At this time, the latest known '69 Z/28 is about 900 units later than N710617. It is possibly what got me started with '69s, as a long-time friends' cousin bought it new in Milwaukee from Humphrey Chevrolet. 57 57 723 X77D80. Only elective option I recall is an AM radio. Still exists far as I know, was for sale a few years ago. Now messed up with retrofitted options.
To be clear, there could be one or more later than the Humphrey car.
