That's an early October 1968 VIN. Body tag is dated 12D, 4th week December 1968. One or both tags are not original to the car.
From ad text:
FULLY DECODED TO BE CORRECT TO THE TRIM TAG.
PLEASE KEEP YOUR NEGATIVE COMMENTS TO YOURSELF. IF YOU SEE SOMETHING YOU DON'T LIKE THEN DON'T INQUIRE ABOUT THE CAR.
Good eye William. Nice to see the number of rally sport Z28,s are catching up with the non RS z,s
We could have a field day with that car. I guess we better not contact him :) Joe
