That is a pre 70 Goodyear dating system. EVERY license plate on post 70 tires has all numbers on a single cavity insert. - variable data - the ones Charlie has shown have a 3 digit variability, which I believe follows the older Good Year system. How are the dates on anyone's original 69 Z tires configured?

No. Because they use the DOT plus 10 digit numbering code which wasn't implemented until 1971.

What they probably are are tires manufactured by Goodyear in the 1971 - 1972 time frame.

They are not original equipment tires for a 69 Z/28. They are replacement tires that you bought at a Goodyear Tire Store when yours wore out.
