Manual Steering to Power Steering

I got a rebuilt K-frame with a power steering box on it. I was considering using it since my 1974 Duster did not come with power steering.

What will I need to complete the job to convert from Manual to Power?

1. Do I need a new steering column or is there a couple I can get?
2. I realize there are two different type of Pumps. What pump typically came with the 1974 Duster?
3. Once I determine the 2nd quetion it will tell me which bracket to buy.

Did I miss anything? There were hose on the box that I may try to salvage. The box came from a 1969 Dart should that information be needed.

Thanks for any assistance that may be given.
