1975 F250 - Power Steering Pump

I am in the process of converting the original steering to a power steering setup. I am recreating a an eBay kit using the CPP series 460 power steering box. I ordered a power steering hose kit thinking the original Thompson pump utilized the same inverted flares as later setups, but have quickly found they don't. I have found a number of fittings that covert from the original lines to the new pump (male inverted to male SAE 45), but have not found one that is female-female. Has anyone come across this type of fitting?

so I used the OEM pump from my 74 and a new rack for a crown vic (I did the crown vic front end swap). I can tell you that this was a challenge. There are lots of kits out there which seem to be correct, and have "some" parts that are, but I still ended up going to a local hydraulic hose supplier to get lines/fittings fabricated. Having gone thru all this, if I were doing it again, I'd go straight to the hydraulic place and let them sort it out. That's my best advice on this - in my experience, I didn't spend any less money doing it myself vs getting the pros involved.

that's pretty much what I had to do, tho I'd built all of them.. and needed one swapped out (6an fitting was my problem child if I remember correctly). Ya this is work that has to be right or it's a fluid nightmare

You can swap the fittings in the back of those pumps, Speedway is a good place to look for fittings
Don't tell the hose shop you are dealing with power steering, you are just looking for fittings
Hell, backhoes run as much pressure, they are just looking for "low hanging fruit" or an easy sale it sounds like, or don't want to mess with the small stuff.

so the local shop said it would be $55 for them to cut the old fitting off, add a ferrule and crimp it. Seems a bit excessive, but I don't know that for certain. I am mostly hesitant as that end of my original pipe is pretty crusty.
