Single wire reverse light switch for 68 Barracuda

Have you got a pic or part#? I MAY have one, I gotta dig.
**edit** have you deciphered which switch you need? I dont see any trans # posted?
What was on the car is not correct. I'm trying to put things back together properly so after all the work (and $$$) Everything should work? Never realized the switch I need is so hard to find.
