Larry, I needed to remake the four front hydraulic lines for my 140 H3 restoration, I bought all the fittings and steel line from hoseandfittings.com you'll need to create an account to view the pricing but it is no big deal. I don't know what your looking for but they have a large selection.
The factory lines use an adapter to go from a male 37° flare to male 1/4" pipe thread. I think the factory lines are 5/16" tube which is harder to find fittings for than 3/8". Keep in mind that tube sizes are taken from the outside diameter of the tube whereas pipe sizes are based on God-knows-what. Pipe "strengths" are rated by "Schedules" with Schedule 40 being the standard and all others keeping that same OD but varying the ID as the wall thickness changes with the schedule. 1/4" Sch 40 pipe has a nominal OD of .540", wall thickness of .088" and an ID of .364". Note that none of those dimensions are .250" (1/4"). Would be nice to know the reasoning that resulted in pipe dimensioning as we know it.
