Here's another, very similar, light blue GMC. Though this particular pic has been edited poorly and looks blown out. And the steel wheels are painted the same color as the body. Original? Got me....but it looks sharp, minus the screwed up the color tone in the photo.
Just one more of the light blue two-tone. Don't want to overdo it in this thread
If nothing else, these will give me a few ideas for when I paint mine...I'd like to go with something you just don't find these days. Hence the '66 GMC in the first place!
