67 Vs 72 Pwr steering

[Arizona oldguy]

I need some advice, I am building a 67 short bed using a 72 frame, the 67 has what I would call power assist steering using a cylinder, the 72 has a power steering box. I have both pumps and all the brackets, it looks like the pulley on the 72 stands farther out than the 67 pump. Will the 67 pump work on the box or do I need to use the 72 pump and then I have an alignment problem. Would I need to purchase a 72 water pump and pulleys ect. Thanks for your help.
