I need a new stalk end switch for the resume/tap down on my 1978 98.

All the usual parts sources dont even have a category for this, oldest I can go back is 83/84 so something profound must have changed. And I just know they are making new ones every day (thats a joke)...anyone have a Help! or Dorman part number or know of a NoS or OoS part (aka used)? The cruise does work, tested it last night, but the end of the button is gone...
