Single wire reverse light switch for 68 Barracuda

I need a part number for a single wire reverse light switch for the 727 in my 68 BarracudThe local NAPA can only come up with the normal 3 pin style and a 2 spade style? Any help would be appreciated Thanks
Ron,
If your car is a single wire to the switch that screws into the transmission, that's neutral safety only.
The reverse light switch will be on the shifter. Does the car have column shift or floor shift?
