Thanks Tim, that is helpful. This confirms that the factory did a contrasting color on trucks. In reference to Brewster Green they say "Gigolo Green striping". I am not sure if that means pin striping in the modern sense or color of what I call the belt line, which includes a double belt line across the sides and back of the cab.
Tim's document raises additional questions. I believe that my truck did not come from the factory with black fenders, rather simply body color. Possibly the same for the headlamp bodies and supports. Was black in these areas standard or an option?
Ultimately, I can do whatever I want but I am trying to end up with a stock look.
