'73-80 factory color+white options.

[Cue-Ball]

I've seen several different interpretations of two tone paint on the pre-81 trucks.

We have the classic two tone with white inset and white roof. This seems to be the most common on the older trucks. I've also seen plenty of these with beige instead of white, or a lighter version of the body tone instead of white (dark green over light green or dark blue over light blue):


Then there's the monochromatic trucks like mine that seem to be primarily very late 70s through '80.


Then I've also seen single body color with a white top (no white insert).


Can someone tell me what was offered from the factory and when? Was color/white only offered early on or only on certain trim levels? Did they eventually do away with two tone completely near 1980?
