manual to power steering swap

I am getting a grocery list in my mind here about what its going to take to do a swap

73 A-body has manual steering now, so far I have a couple good running gear box cores and I am thinking I will get a new pump.

so far I have:

power steering column with shorter shaft.

A couple power steering gear box cores (one was running in a car a week ago but is greasy)



What I think I need:

pulleys

new pump

new brackets (bouchillon performance has them)

power steering lines.


Anything else or any problems I can expect?? I have never had an A-body with power steering before.
