No pics of the original style set-up, but I will state that it worked poorly at best. It had one switch (neutral safety) activated by one rod and a second switch (back-up lights) activated by a second rod. The rods easily became bent and/or out of adjustment.
The only simple, solid, (& low cost) conclusion that I have been able to come up with for at least the NS switch was to fabricate a bracket that mounts to the tailshaft utilizing the shifter mounting locations. The bracket holds a simple push-button switch that gets activated by the butt of the shift rod when the car is in park:
