Last pics are of screws and overall appearance -
Just wish I had bought multiples of everything I started getting from GM starting in 1980 - that's when I figured out what the X77 on the cowl tag meant, and found out how to get the original documentation. As years went by, I managed to accumulate a lot of NOS parts, but I only had 1 car up until 1992, and then only '69's until 2011 when I added the lonely '68 Z (by selling an LS5 '70 Chevelle).
You live and learn, constant process. That's also why a geez like me likes the site -
