Prior to cutting anything, I torqued everything down and checked the pulley alignment:



Pretty dang good! Still, you don't want your belt walking off any of the pulleys, so may as well make the alignment "right". This means that the outer (main) PS pump bracket needs to go back another 1/16" or so. There's a small boss on the WP where the pivot bolt goes, and it's about the right thickness. I'm going to mill (file) that boss down flush with the main part of the pump, and see if that does the trick. Doing that won't affect the operation of the pump at all, since nothing else bolts up there (AFAIK).
