7/8"x14 nut

Speedway has one for a Corvair box for $3.95. McMaster-Carr has various types of locknuts and castle nuts.
I think they are 5/8-18...
I need a half nut . A full height nut won't allow me to tighten up my Pitman arm completly . The Corvair won't work. I have a '54 Ford truck steering box and lost the nut.
