Finally got a chance to reply. Looks like he figured it out for 69.
However my car shows GG on the trim plate ,nothing else. ( 04 Norwood car). In the late 80's, early 90's the old man who shot the stripes approached me at a show proudly giving some history of the car. Done at Milad Chevrolet in Amherst. Honestly I sort of didn't believe him and put it off over the years.
Flash forward to a few years ago...#1 calls me, we chit chat ,tells me car was stripe/console delete. Plus some other cool history.
As my paint/body man was obtaining measurements ,told me they were slightly off per CHP, this site etc... So there it is. Pretty sure the mice ran off with the build sheet ,if that's what it was , almost 30 years ago.
