The pump is sitting where the alternator use to sit. In fact I used the bottom-mounting bracket for the alternator as the base mount for the pump. I custom made all the brackets for the alternator and PS pump. Finding places to secure the brackets to the motor was interesting, as the F motor...
I just finished putting a Toy IFS Mini power steering box on my 65 FJ40. I'm happy with how it's turned out so far, but I haven't had a chance to use it yet. I went right into swapping in an SM420.
You can see pics of the install here. http://www.dttm.net/DBoard/viewthread.cfm?TID=86
