quarter panel vents/scoops?

this may be a stupid question but what are the little vents/scoops on some 68 quarters? thanks, lance

Most scoops --like on the Shelby or Califonia Specials, are just for looks. However, there are kits available (Maier Racing) to make the scoops functional and duct air through the quarter panel into the wheel well to help cool the rear brakes.
