X on on right on top of the box only flat tip screw sticking up out of a lock nut.
For the steering - Start by adjusting the slack adjuster - it will be a locknut over what appears to be a bolt with a screwdriver slot. Put a screwdriver into the slot to hold it and back off the locknut. Slowly turn the screwdriver clockwise while rotating the steering shaft back and forth until there's very little to no play. Hold adjustment bolt and tighten the locknut. With power steering this is done with the engine running. Once the slack is adjusted out of the steering box, look at the top of the steering column (still under the hood) under the master cylinder. There's a heavy fiber washer (sometimes referred to as a rag joint) (1/2 ton only) that makes a coupling in the column, usually this is worn out and the cause for excessive steering play.
Steering adj #2 all you have to do is on the steering box you will see a threaded screw with a jamb nut keeping it locked down. put a screw driver on the screw and loosen the jamb nut, then with the jamb nut loose , tighten the screw till it stopes, then back off counter clockwise for one full turn, then holding the screw, lock down the jamb nut. take the truck for a ride and see how it feels, if it is still too sloppy, loosen the jamb nut and turn clockwise a quarter of a turn and retighten the jamb nut. if the steering is too hard or feels like its binding , hold the jamb nut and loosen the set screw a quarter of a turn from your initial setting.

Thanks fellas! I'll be sure to try those out tomorrow. The rag joint appears to be allowing no play (tried grabbing above and below it and rotating opposite directions). However, if I grab the shaft just before the steering box, I can hear it rotating and I have a bit of play before the pitman arm starts to move. Slowly getting her ready to hit the road again!
