Looking for a single wire Neutral safety switch

[Stewsta]

Swapped the 318 for a 440 in a 66 coronet column shift and need a single wire NSS for a big block 727. I know I can use a 3 pronger but id like to use the wiring Ive already got. A link to a place to purchase one would be great as well. Thanks Stew
