These vent window assemblies were parts that came with a 1940 Pontiac convertible. I don't remember why I didn't use these instead of those in the car (30 years ago) Three bodies were used on 1940 Pontiacs. 1. The new Chevrolet body (also used on Olds) 2. Carry over body from 1939 also used on Olds, Buick and LaSalle. 3. The new Torpedo body , also used on Olds, Buick, Lasalle and Cad. Convertibles in all three bodies.
These may be for only the 39 bodied cars. Can send more photos to interested parties.
