Power steering pump?

Trying to finish up my duster and need some advice on power steering pump. It's a 74 /6 car. Factory power steering box. I dropped a 340 in it with shumacher engine swap mounts....still has the /6 K member. Was wondering what to use for a power steering pump, pulley and for the brackets. I'll be buying everything new. Not really worried about price, just curious what will work with the /6 K member Engine has aluminum water pump if that matters, and march pulleys on water pump and crank. Any advice?
