Power Steering Questions

Hi everyone. Now that I have the 440 Duster project running well, I'm looking at making it a little more comfortable and I need some help/ideas for adding power steering.

Currently, it looks like I have plenty of space. The engine if offset quite a bit to the passengers side, it has Schumacher headers and the battery has been relocated. Car was originally power steering /6 that the previous owner converted to manual. It has the power steering shaft with the adapter, so that should make it easier, right? Its currently set up as floor shift- not sure if that makes a difference.
I know I would need:
-Power Steering Box
-Power Steering pump (is the big block and small block pump different?)
-Pressure and return Lines
-2 groove crank pulley

Am I missing anything? Any thoughts from the community? I'm running an 18x9 in the front with 255's and turning it in parking lots in a nightmare.
Thanks!
