Headlight and wiper switch removal - 64 Valiant pushbutton

On the headlight switch reach behind the dash and find the little pushbutton on one of the sides. Push it and the knob and shaft should come out. Unscrew the funny looking nut (might have to hold the light switch) and the switch will come right out From the back. The wiper knob is held on by a little Allen screw. Remove the knob and follow the same procedure as the light switch. DON’T FORGET TO DISCONNECT THE BATTERY FIRST!!!
Thank you Dartman. I seem to remember removing switch shafts that way like 40 years ago and I don't think I've touched one since. Any idea how to remove the push button assembly?
