Steering box leak

[kknip]

This is on my father-n-laws 74 Torino.I figured the box is the same in general with truck ps boxes.It appears to be leaking out of the worm adjustment screw,under the nut.Is their an o-ring under there that I could replace?Or will I have to take the box apart? I have not delt with the internals of the steering box.
