Adjustment on a sweet steering rack

I noticed a bit of play in the steering wheel of a car I wrench on. I never tore into a rack and pinion on one of these cars yet, but if I understand correctly the adjustment is on the top side (big slotted screw/plug). I was going to tighten it up this week, but thought I'd see if there's a proper way, or any damage to look for before I just tighten it til it feels good. I don't want to overlook any potential issues or cause more problems than I'm fixing. Thanks!

I have the same problem.

If it has more than one season on it, it needs new rack housing bushings. Free play is not adjustable.

Thank you. Not what I was hoping for, but I'm sure it's time for a rebuild. It came in the car and probably has a few seasons on it.
