Exacto knife to cut out the triangle. Mount a piece of clear styrene to the bottom of the triangle. Then a small upright piece to close it in. If functional, you'll have to make a round hose fitting placed at the base of the triangle inside the car.

ok, thank you for the info! and what about the sides of the vent?

It should have some curve to it.

Here's a pic of the ones we use on our race car. Look 3/4 down the page.

By the way, the are all a little different in shape. Like the Mustang hoods are flat on the bottom with the opening to the rear of the triangle so they don't realy have a side so to speak. But this should give you some ideas on how to build them.
