Rich, I also have a 68 firebird convert with a white top and parchment interior. I am thinking of painting it a dark blue and was leaning toward the 2001 Chevy s-10 dark blue called "indigo blue" GM paint code WA9792
please post some pictures when you get it back from paint cause I'm about 5 months away from painting mine and I'd love to see what you decide to go with.
