Thanks to Mark Price, I solved my power steering pump (pulley) problem -- thanks Mark! -- and now I have one final trivia question.
*** Does anyone know what (if any) AMC six had the pump on the same side as the steering gear, but uses flare fittings? I need to buy a hose... and trying to avoid custom.
As far as I know, most of the six cars with pump on the drivers side were O-ring'ed, (80's Concords, etc). I've got a 70 steering box, and an 80's pump from Mark I was able to swap the outlet fitting to make the newer pump flare fitting.
