Do you remember what size nut it is?
no, sorry, I just loosened it up, turned the inner dial with a screwdriver to take up the slack that was there and retightened, takes like 1 min.
17mm
Mine was way not normal, and I've replaced bushings, checked/adjusted bearings, bla bla bla... So I checked how much it "could" adjust, it was about 1 1/2 turns. I did 1/2 turn for starters. And you MUST have that screw set wherever it is when you're retightening that nut. it can move around.
I did try the 17mm and it seemed very loose. I'll try again. I don't have a 15 or 16mm wrench to try. It's highly unlikely I have a different size, than whatever the other have. Maybe I couldn't reach there all the way... IDK
Update
17mm is the correct size. I probably did not place it well the first time.
I can't for the life of me turn that wrench at all. Tight space to work in, maybe 1.5" room to turn the wrench, but it won't budge.
It looks like I have to take the battery tray out to make some more room in there. The longest screwdriver I have is comes about 1 inch below the top of the battery tray. No way I can do it through the wheel well.
I got work ahead of me this weekend.

Just as a side note, the washer under the nut is a sealing washer and may leak after you brake the nut loose. I adjusted my steering box and the washer hasn't leaked, so I consider myself lucky. If you're not in a hurry you probably should have a new washer ready before you brake the nut loose.
Pictures?
I had play, ended up a loose panhard connection. There was slop from the bolt being boogered up and not tight enough.
Have adjusted GMs before-the most wear is usually in in the "straight-ahead" part of the sector gear. If it's adjusted tight in the straight ahead position it may bind (interference fit now in the gears) at the far turned positions. I had good luck adjusting with the front end off the ground and hand-turning (left to right) the wheels through the steering travel. You could feel the bind much better that way. There should be NONE-as stated will damage. Fix the loose parts in the steering etc to fix it. Have looked on youtube and don't find any good videos on checking .
That's what I did, all the slop was in the "straight ahead" area of the steering, so I adjusted for that. I'm really close, but I'll probably leave it alone for now.
And I've checked/fixed everything else beforehand.

There's no self-centreing as far as I'm aware with the steering boxes, and there's no centre 'detent' position. One thing I need to check with mine is that I lined the pitman up properly as I'm getting a bit more steering towards one side of centre at the wheel than the other. Been 6 yrs since I fitted a re-co box. A later 105 series box would be nice, subject to the price of about A$3k for a new one.
Just an add on to this thread, from another forum which I found as the best description for adjustment, makes sense..

loosen the screw first and then feel for the contact on the tighten, it is subtle shuttle cock shape.
would apply to most steer box adjustments, probably shouldn't do it until everything else is checked first, tre's, tyre pressure (not to high), rubbers, alignment, toe in, bearing pre loads, knuckle nut torque, spring u bolt torques in front and back, stabilizer, shocks, damper..anything else?
It is tempting to do the deceptive easy box adjustment first, but it should be done as last resort.
Adjusting 80 series steering box
My 80 now drives on rails as I've adjusted the steering box The fwm isn't any good so here's how to do it. 1. Best after front axle rebuild but the below applies if you just want to adjust. 2. Slacken adjusting nut. 3. Hold adjuster screw with screwdriver and remove the nut. 4. Put car on front...
