power steering pump fittings for a mustang II power rack

what type of fitting are needed to connect my mustang ii power rack to the old style 1968 ford power steering pump? Are they sealed withy an o ring or An fittings ? It dosen't look like an inverted flare since there is no raised piece in the center for the flare to seal too. Any help is appreciated. Thanks

Looking at my '76 shop manual it shows two versions of the TRW style pump. One has the tapered compression style outlet on the pressure side and the other (model HBA-DA) has a 3/8" tube seat that goes in to take place of the missing taper. PN on the diagram is 374480-S The return und just clamps on like the '68. Stu
