K20 Power steering pump

Can anybody tell me what pump came stock in my 80 GMC K20?
I think it's a Saginaw P series, are all P series the same, except for the bigger reservoir?

I'm looking for a stock replacement with res in chrome.

Re: K20 Power steering pump

I believe the pressure is different on a hydro pump.The valve can be changed from one pump to another.

Re: K20 Power steering pump

Ghetto, Ive seen that done. But your using your stock non-hydroboost pump right? And it works fine.
