Picked this up at a swap meet decades ago. Never used it. In looking at the instructions it appears to be a kit for full size or Fairlane. However, the PS pump can is definitely for a Mustang. It appears this kit was available through Ford for those cars that had factory power steering without AC and then added AC from the dealership. It required changing the PS can to the angled spout to clear the AC bracket and compressor. I don't believe the kit is complete as it shows that a pulley must be changed and there was no pulley in the kit. The dip stick appears used but it is correct for the can.
