Wiper/Lights Switches Re-Located
Aloha Dan!
Hey here is a picture of my 71 duster. As you can see I think you will have plenty of room for the light and wiper switches. I would put the wiper at top and the light switch down on the bottom. The wires for the lights are on the side but you could mount it with them facing down. The wipers will plug in with plenty of room. No need to extend the wiper wires. The blue, pink, green and red are the wiper wires on the harness. Looks like they'll reach your wiper switch in either place.
Good luck and post pictures when you are done.
I might do the same to my gauge cluster!
Aloha, Mike
