Where can I get pictures of 1979 Chevrolet truck color combinations offered by GM?

[DENTON]

I want to paint my truck back to factory 2 tone colors just like it came from the factory. My problem is I cant find anything online that shows/tells what 2-tone options GM offered in 1979 as factory color combos. Where can I go online or where can I go to buy a publication that will tell me the factory 2-tone color combos GM offered on these trucks in 1979? Every '79 Chevy I see seems to be a solid color and I want to go white with another good looking color.

Thanks
