Will 1964 Chevelle Vent Windows Interchange between a 4 Door Sedan and a 2 Door Hardtop?
Thank You for the help.

I'm thinking no. Parts book shows ventilator assemblies for 'Spt. Mdls.' and 'Non Spt. Mdls.' I would assume that 'Spt. Mdls' refers to 'Sport Coupe, convertibles, and Sport Sedans' and the 2-dr hardtop 64 is generally referred to as a Sport Coupe. First item is the ventilator assembly itself, second is the glass. Weatherstrip and other items are different as well.

I have always heard that they are different, but I have not verified this myself.
