Is there a known date for the upper firewall paint detail?
I know from personally tearing down 1584 (March 31st, 69 build date) that the firewall (and even the tops of the inner fender panels) showed signs of having grabber orange paint on them (thanks to my overuse of a high powered steam cleaner), and then were blacked out at the factory. Yet, I've seen other cars, both before and after, with a painted upper firewall.
Was this an error during restoration?
Were only certain colors subject to the upper firewall black out?
Or, was there a certain time period where the black out was a simple production line change over, or change out?
Just curious this cold and early AM.
Thanks in advance
Bill
