[urq] Headlight switch compatibility

[K B]

Hi guys,
 
I have an early 83 #106 and a friend and I are replacing the fusebox and a good majority 
of the wiring (very long story). I got the headlights working and then started having strange intermittent issues
with the lights. 
 
I am suspecting the headlight switch and I wanted to find out if anyone has used a switch from a 4000 and or coupe or which ones are compatible with our cars.
 
Thanks
 
Ken
