Where to get a new or rebuild A/C switch?

Mine in my 66 cuda was broken like that i carefully removed the broken ends from the tubing and stuck .41 safety wire in the holes of the control/slipped the broken parts on and super glued the broken tubes back in place [that was in 2006] after they dried i [carefully] removed the safety wire, works like a champ. Got luckey i suppose plus i'm cheep.
