Power Steering Return Line Hard Line

[D-n-Tyke]

What years use the same power steering return hard line, the tube that screws into the power steering box. Previous owner took that with them when they pulled the motor so now I need to find one. Was hoping to find one in a junk yard but later models are easier to find then our 72 and down years. Am I right to assume that atleast up thru 1987 would have the same return tube as our trucks? How about later years? What about flare vs o-ring? Do I need to worry about that starting at a certain year they switched to flare? As much as I like junkyarding I am not looking forward to this hunt. Anyone got a spare laying around?
