Steering box adjustment

[Lenny51]

My steering wheel on my 51 has a lot of play in it I turned the top adjustment in . There is a plate underneath that you can turn looking
from the bottom of the car do I turn it clockwise or counter clockwise
& how much do I turn it .
I am getting a new idler arm kit from Chris , the king pins are tight &
the rest of the linkage feels tight . The wheel bearings have a little
play but I cant go to the next cotter pin hole
Thank you for any help on this
