Driver's air vent...do I need it?

Oh, the old open container behind the door trick, eh?
Got to say I never considered that. But I always thought the Mopar style of fresh air vents are simpler and more efficiently than any other design. I want to keep my Dart simple so I'm keeping the fresh air vents in my '69 Dart and doing without air conditioning. We just don't have that many continuous hot days here in SoCal.
Besides, when finally finished I want to hear the beautiful sound of a sweet-running smallblock.

Way back when, I have used the vent for that. (open container stash)
Between the two vents you can keep a 12 pack cold in the winter also.:D
