Anyone know the nut size off hand for the sector shaft nut? Thats the nut that holds the pitman arm on the shaft in the steering box for the slower ones in the group... (Like me before I found that its actually called a sector shaft while searching for the nut size )

I'm away from the truck and need a socket for it.

 

1 5/16 just had a wrench on mine today, it was hernia tight

 

Thanks... Got one picked up and got the nut tightened!
