looking for diagram of a '68 steering coulmn

The top/bottom collar are held on by the 2 square headed bolts that have a cerrated nut on top. You can see it in the top of my 1st pic at about 12 o'clock. These fit into square-ish holes in the lower column collar and get CAREFULLY tightened. In the lower pic you can kinda see them on the towel.
