Windshield defroster vents

I am going to be making some Billet defroster vents for a 65 dart that we are currently building. I was wanting to see if there is any interest in these. I know that there are being reproduced in plastic, but these will be aluminum. I currently do not have a price, but I will soon. 62-65 B-BODY,63-66 A-BODY & 72-80 TRUCK all use the same vent.
