Power steering hose with internal fitting

Alright, I have just about given up. I have already ordered three parts at the advice of Advance (supposedly for a 71 dart). None of the parts were even close to being right. I finally started researching myself and found the right part (I thought) but the connecting piece to go into the power steering box is an internal piece instead of external. Where can I find the right part to make this work? I don't want to jimmy anything, I just want the piece I need. Can someone give me a shout out?
