A few errors in your original answer, running boards were always black, never body color. Rims on deluxe (5 window) trucks were body color with the contrasting stripes, number of stripes depended on wheel size. Non-deluxe cabs came with black wheels, no stripes. The "body ribbon" you speak of, I will assume you mean the belt line of the cab. That came with a pinstripe, contrasting color, which one depended on the color of the truck. If deluxe wheels, same stripe color. All cabs came with the stripe regardless of deluxe or not. If the original poster obtains a restoration pack from GM, this information will be in it.
