I just saved section 3 from my P30 Chassis Service Manual (Steering, Suspension, Wheels, and Tires) as a separate 4mb .pdf file, but for some reason I cannot attach it here. It has some diagrams. If you email me at email@example.com
I will reply with the file attached.
I have read posts from guys who have improved sloppy steering with an adjustment at the steering box. We had a big improvement when we had the "rag joint", aka steering coupler, between the column and steering box, replaced.
