1970 Dart Swinger Heater Control Knob

[Big Guy]

Hi, I am trying to find a Heater Control Knob for my 1970 Dodge Dart Swinger. Any suggestions to where to find one or if anyone would have one for sale, that would be great! I have added a picture of the one I have but need a second one to add to the second lever.

Shouldn't this be down in the wanted section?
