if you have money to burn; an aftermarket bracket is the easiest solution.
i made all of my front end accessory brackets for almost nothing.
the power steering mount was the easiest.
be sure what ever you do that the bracket doesn't move.
i took these when i had to change out the ps pump when my rack went bad.
i believe the pump is a 68 truck pump, though the pumps were all the same from 60s thru 00s.
they used the same pump in different housings.
