Steering Column Bearing Replacement HELP

Here is a couple pictures of the 67 column.
Different size outer tube then the 68 & 69 takes a different bushing/bearing.
Has a set screw lock collar and spring to hold bushing in tube, changed to a sheet metal screw
in 68.
Inner tube slips into bushing on lower end and is keyed into the lower collar at the upper end.
You take the bushing out and the inner tube is no longer held in place allowing lower column collar to rotate with the tube.
Also inner tube may be slipped out of lower collar if set screw is not tight. This set screw is
accessible thru hole in lower collar. 67 only. No access hole in 68.
