The Dodge Challenger Message Board

I have a 1970 SE and my ventilation system is only working in the middle under the dash and I´m missing some parts that open and close the side openings. Can someone post a picture of how the VENT cable goes and how it is attatched to the dash (which I guess it is?!) As it is now I can reach down and open/close them with my hands but it would be nice to get them to work correct...secondly: does anyone know where to find these missing parts?
