Ignition switch jam nut size 2001 t35

[Parfleche]

Dear Folks,
Does anyone know the thread pitch and size for this nut. I lost it, the ignition is only a couple years old. My imprecise measurement is 7/8 across outside of the thread. The ignition was purchased from NH, made in Mexico.
Thanks,
Steve

I would either:
1) disconnect a battery lead, remove switch & take it to the hardware store. In town nearby is a fastener business that sells everything you can imagine.
2) get part number from New Holland dealer & order it

Went to 3 hardware stores, nothing over 3/4" in jam nuts (they all had the same stock) NH only has the ignition switch with the nut, $139. Auto parts store did not know anything about anything. I'll try Tacoma Screw next, or throw a clamp on it, I prefer a jam nut that fits though, either plastic or metal.

You need to know TPI
This is McMaster Carr 7/8" 20 TPI panel nut.
I'd rather metal than plastic.

Found the nut size, m22 x 1.5 if anyone needs one.
Thanks all,
Steve
