1964 power steering

[Tramp1964]

I'm in the middle of putting in a crossmember from an 81' with power steering and disc brakes into my 64' with a 230 and 3 on the tree. What I'm needing to know, is there anything other than the one power steering pump bracket set from 4-5-6 Chevy in KC to make the pump mounting work? And can I use the pump from the 81' or am I going to have to find something different to work. Everything else I've managed to work through, but this has left me scratching my head and pulling mair.
Thanks for any help.
