I opted for a new headlight switch I was able to source and installed it this morning. It was much easier than I anticipated, but only because I was able to twist myself around to get in the right position to see and handle everything. I'd say if you happen to be more Rubenesque in size, have fat fingers or can't squat or lie down that low it is not a job for you to attempt.
I didn't take pics but it's pretty simple. First, I disconnected the battery. I then pulled the black headlight knob straight off, then unscrewed the retaining collar for the headlight switch which allowed it to be pushed backwards and out of the dash. There was no other retaining device on my car. I could feel that the wiper switch and the bulb fixture for the shifter indicator (automatic car) were helping to hold the switch in place so I then unscrewed the black knob for the wiper switch and pulled the shifter bulb straight back towards the firewall to remove it from the housing. This is all done with feel, no eyes on any of this, hence the need for smaller hands, acrobatic ability and patience. I was then able to rotate the headlight switch with all it's wires attached up, then towards the firewall then down towards me again which gave me enough wire length to easily do the job. I could now see the markings on the switch so I knew which wires I was removing. I simply started with the double wires since there is only one set of those and worked my way around noting the one spot that was unused on my car. Once finished I rotated everything back up in the reverse of how I moved it down originally, replaced the wiper switch, bulb then finally the headlight switch. I am not sure if there is anything to help position the switch but put your black knob back on before you tighten the chrome collar fully and be sure it is oriented properly.
I was concerned about wire insulation cracking but these were insulated with fabric so it was not an issue.
My old switch did simply come uncrimped from the base, so I will take it apart just to educate myself on it's design and may use it as a spare for when this one goes out in another 50-years.
