Almost a year ago (I looked it up) I wrote about how I doing the steering box in my 1967 122s. I have finally completed the job. It's not hard. Getting the pitman arm off the old box was a pain. A gas station did it for me with a puller on the air gun. Make sure you line up the splines so the wheel is straight when you put it all back. I marked the box it self on the extreme right turn, left turn, and used the middle as the straight wheel. Use a new coupler also when you are done. Put oil in the new box.
