One of my nuts is missing!

Hi,

I'm looking all over the place for the nut that holds the pitman arm on my steering box. It's an F3 box. I've been all over the local yards looking with no luck. Any help is appreciated. Thanks guys.

Also, here's a pic of my finished frame...

 

what size is the thread? i'm sure you can find a jam nut and lock washer from a fastener supply co

 

I've been all over... No hardware store or fastener place seems to have it. It's apparently a Ford specific thread...? Not sure on the count.

 

is it the same as the one that would come on a 1960 Ford Pick Up if so I have one for ya P.M. me with an address and I'll put it in an envolope and send it out in the morning.

 

Try a Cat tractor store. They carry a large supply of grade 8 nuts and bolts. I think you are looking for a large castle nut that takes a cotter pin. Ford used standard thread counts but sometines used odd sizes like #12NC for the door hardware in the '30's-'40's cars.
