[6pack] Heater switch source

[Kendall Larsen]

Hey List,

My heater switch fell apart, and I've put it back together before. But this time the springs that make things work are missing. (Long gone since i had the switch plinth off for almost 6 months when i was replacing the engine.) The switch does not seem to be available from the big 3. Any ideas where I can find one for sale used or new?
