Chevy's Lookin Good.....lol

...and I've seen that truck in the background of another shot.

If it's the one I'm thinking of, I like that body style.
(1967-72)

Not sure when someone applied the "glamour era" moniker, but I don't care for that.
What makes them glamorous?
I do know that those years did not offer a crew cab or even extended cab.
gm was WAY late to that party.
Dodge and ford offered crew as early as 1964.
gm was 1973.
Extended was 1970 (IIRC) for ford and 72 for Dodge.
gm didn't get that until the 1990's IIRC.
