Federal or Saginaw? What's correct?

Getting ready to start my '70 RT/SE resto. My question is what power steering pump is correct for a 383 HP that year? Thanks

What is needed to convert a federal pump car over to a saginaw pump car? I have the tear drop shape reservoir and it is leaking. I need to replace or fix it.
