Power Steering Pump Fitment

So I just swapped my 74’ Slant Six k frame for a 72’ V8 k frame and I thought the pump mounting was the same but it’s not quite. The pump doesn’t sit down far enough to be aligned with the mounting holes. Seems that the pump is hitting part of the k frame. Is there a difference in the years for pumps and I don’t know if this V8 k frame was manual or power either. My car has power steering.
