Turns out that the power steering pump has a vertical rod to control the tension. A square nut on top moves it until the lower adjustment stud/nut can be secured.
Yes, you can use a lever to move the A/C compressor and tension it, but the power steering has a different mechanism. Not sure if this only applies to later model with A/C; perhaps if there's no A/C there's no need for the vertical rod, as you can get a lever on it directly.
Sure wish my shop manual had late model info in it!
