Pitman Arm location on shaft question

[beaterku]

I am buttoning up the front end of my truck and noticed that the Moog pitman arm does not go on the Redhead steering shaft as far as it should. The drag link runs slightly down hill from passengers to driver side. The stock box and arm showed about a quarter inch of threads when torqued down. This new setup is flush with the nut.

My gut is to remove it all and inspect to Make sure there are no burrs on the shaft and arm. Is this enough to worry about?

Thanks!
