I know of a local one that is blue now but was originally bronze, I believe. In the St. Louis area.
There is actually a 1967 b5 blue 4 speed, my dads 68 b5 blue 4 speed, and that 1969 gtx auto here within 10 miles of each other.
I just bought a 68 Sport satellite convertible off here and was going to be "that guy" to make it a gtx, but I have to sell it.

EDIT: I also want to say that there was a 1969 for sale at a local classic car place, but doesn't show up on their website anymore. It was Fastlane Classic Cars in St. Charles MO. I'll have to look through my old phone to see if I have pictures.
