I am trying to replace all my dash switches in my '61 Hawk with NOS or re-pops. I believe between Stude Int., Stude Dot Com and Stude West I have located all but the "Air" switch. Any sugestions for other vendors for the air switch or others? I want to replace the heater and wiper levers also. My car's interior was subjected to a long period of dampness and I do not trust the electrical system.
