Looks like the full size car map lamp mirror. It is marked "guide". Not a strong area for me beyond having seen these mirrors in other GM cars of the period.

Looks like the mirror in my 71 Malibu convertible.
I have another one in a box somewhere.

I've never seen them on these trucks but they were available on most all GM cars from 1969-72; Chevy, Buick, Olds & Pontiac. (72 came with a black back)
