Well, most any v-belt style 351W PS bracket and pump will fit on the motor, but given all the combinations that Ford used, you really need a matching 'set' to be sure it'll line up. Best bet will be if you know what pulley combo you have now (what exact vehicle it's off of), find somebody with a Hollander Exchange manual and look it up.
Use it all from one donor ! Hard to tell what you have if you don't already know . I used 400 M stuff on a late Windsor , it all worked out great
