I've seen original paint 67's with white tags and without white tags.
It was obviously done to indicate something. Seems strange if it was to highlight the tag cause the tag info was also on the UOIT. Also interesting cause there were other ways in the system to flag things and the blackout paint was specifically there by Marketing request to cover assembly plant markings. I've never observed a pattern to it, but the sample size is small since most firewalls have been repainted over the years. Never seen it on a 68 or 69.

I'd say that it was for Fisher since the tag and it's info was for Fisher (and it would seem strange for Chevy to be marking a Fisher item). Since it was done after firewall blackout, that indicates that it probably was for the Trim Shop Operations in Fisher.
