I have solved this. Another thread on here mentions that Pontiac used a wider belt for the PS pump. It appears that my double groove WP pulley and my double groove crank pulley, with the single groove pulley behind it, have a wider groove in them for the PS pump belt versus the Alt groove. Bought a wider series belt for the PS pump and now they ride at the same height. That will get rid of the belts trying to spin the pulley at different speeds making weird noises and causing wear. I don't remember where I sourced the AC pulleys, been too long ago, but I got them when I added factory air to my car and needed the faster speed for my water pump.
