Specific to the 180, but probably same on most models? Are the hard lines with flares a 45 or 37 degree fitting?

My guess is 45 just because they look like it (with my bad eyes) and the thread sizes match up to SAE rather than JIC. But I'm not sure.

EDIT: Maybe I need to be more specific. Looking at PTO and power director lines. Are the lines on the high pressure side of the steering valve JIC and on the low pressure side SAE??

The inverted flare lines are probably 45. The other I believe are 37.
