I located and by mistake purchased an "NOS" 914 Head Lamp Switch for the model year 1972-76 cars. The p/n is 914.613.414.15
For reference, I'm posted these photos of the switch used in the 914-4 cylinder cars (1972-76).
This photo shows the part number...
The switch did not come with the threaded collar, I'm again looking for "NOS", I have used...
Here is the new switch with the rubber knob installed
This is an NOS rubber knob Glenn Stazak sent me. Perfect!
