Well as you know these are hard to get a picture of, but I think I was getting excited about nothing but no adjustment or grease ever. For reference this is the one in my '73 (power steering conversion):
It's hard to see but it's definitely stepped.
I pulled the other one apart, and despite having a bunch of play, it really looks pretty pristine. I'm going to put it back together, grease it up and run it.
It looks stepped on the left, but it's just the paint scuffed off. The right side is unbelievably straight. You can feel a little ridge, but nothing like the '73. The cast piece looks great and the other tapered bolt piece looks great as well. ETA: I'm starting to wonder if this one didn't break down many years ago and has sat for a very long time.
