Do you still think that I should just put a wider belt on the power steering to see if it will stop squeaking and seizing?
Yes, fixed my problems. Factory manual for 1973 shows same width belts, but earlier pre 70 some models used a wider PS belt. My pulleys came from an unknown source. My belts ride at the same height in the double pulley grooves now in my WP and crank pullies. Fixed my belt noise.

Check gates site for belt specs. My PS belt is Gates 9530 – ½” X 53.375” long.

"one is part 15500 and the other is 15515" those are the same series belts, 15 series, and the same width? Pulleys have two different groove widths is my thought.
