1968 Dodge Dart Convertible Fresh Air Vent Doors

Been looking for those two hinged metal doors (with the small handle). These attach to the two fresh air vents on the interior. Mine rusted away 20 years ago and I can't find them anywhere. Photo attached of one that I found online (someone was selling the entire assembly).

Also, does anyone know if there is supposed to be a screen or filter somewhere in the fresh air vent assembly to keep debris from flying through?
