Hi Dave,
Here's yet another option.
I don't know if you can find these over there as they were a bit hard to find here new.
I've posted a couple of pictures in my gallery of the serpentine belt and pulley installation in my car (there's something harmonious about putting serpentine belts into a serpent

).
I used late-model pulleys as found on F250/F350 pickup trucks over here that were equipped with 460s. These stock steel pulleys should last longer than the car!
I'm very pleased with the pulleys and belts, and with the custom power steering brackets made by the builder.
Let us know where you end up,
Tom
