Power steering pump pressure fitting

[R.O.B.]

I'm converting my 67 C20 to power steering, and I've bought a gear box and hoses for a 79. Yet I bought a pump on Facebook Marketplace from a guy that said it would fit 60-70's Chevys. Well, the pressure line connection on the back of the pump looks to be o-ring style. I need a new fitting to convert to the flare connection. Does anyone know a part number and/or where to go?

I have a ‘72, when I replaced the pump a few month back, I forgot to remove the fitting and the new pump didnt have it. I quickly ran back to NAPA and told the man at the counter. He went in the back and found my old pump and removed the valve for me. He said I would likely not find one anywhere…at least new.
Good luck!
