Need a favor from those with SBM and power steering.

Reviving this one. I was back at it again this weekend. I added the missing triangular plate in the PS mounting brackets. Mine was missing even though this set-up ran fine for many years. Still getting a loud screech from the pump or belt starting at 2300RPM. The alignment (straight edge) looks good. I removed the belt and slowly spinning the pump pulley I do get some runout in two places. Bent pulley??? but how??? There is also in/out play on the pump shaft but I had that with the replacement pump I tried. That pump did made the same noise and would kind of point at the pulley but how would it have gotten bent?? I don't have another and don't really want to keep swapping more parts on this. Any thoughts? No issues for 10 yrs with my set-up.
Here is what I have tried.....
Isolated power steering issue. Remove belt, goes away.
New Gates belt. NG
Checked noise, play or wear felt in pump bearing. All good.
Replaced pump briefly. NG. Pump lines were different and did not plumb correctly and shaft end play worse than mine.
Swapped my original pump back in.
Shimmed brackets to better align pulleys. NG
Swapped in missing triangular bracket. NG

I do notice that I can move the sound in RPM range with belt tension.
