69 Dart Convertible SAVED FROM THE Grave

under both sides of the dash there are 2 (about 6") round vents that go up to the cowl.
the covers that you would use (if you were to use vintage air) are call hats..My error.

The round vents are designed to go close to the cowl while the water that goes through the cowl runs out the fresh air comes in from those. In other words they are higher than the actual sub cowl. If i could dig up a picture I will send it to you.
