Does anyone know where I can get the tool for removing the retainer nut for the wiper switch on a 1964 Valiant? I want to get at the pushbutton mechanism and I was able to remove the headlight switch retainer with a screwdriver and small hammer but the wiper nut won't budge. It is just getting chewed up. I could try and make a tool but it would be awful finicky with all those tiny slots. I would much rather buy a ready made tool.
