It appears to be standard 3/8" inverted flare but I don't have a new inverted flare nut available to prove that or if it has some special thread. Unless someone else can confirm, I'll be glad to pick up a nut and investigate farther but if it's an urgent need then I may not have the info that quickly.

Those fittings are classified by the outside diameter (OD) of the tubing. So take your wrenches and find which wrench fits over the line. For example 7/16 wrench.
The flare is standard double flare but that is a high pressure line and you need to buy the line pre-bent. The threads are SAE fractional. Any hydraulic place that does forklifts should be able to help you if you don't want to buy a line from the popular suppliers.

I have tried a 3/8" pipe fitting, and the threads do not fit. What I have found to fit is the #6 fitting for an AC system. A #6 is the smallest of three lines in the AC, and connects condenser to drier. The other two AC lines, #8 and #10, are larger. So if I can just figure out what the #6 line, male fitting is correctly called, then I have the threads figured out.
As for the flare, I understand there are 45 degree angles and there are 38 degree angles. The 38 is per AN and SAE spec, but unsure about the 45. Also, there is a spec sometimes called, "power steering only". Also, of course I'd want the PS fitting to be mild steel instead of aluminum. So, I was hoping someone here would know, without me having to swim upstream on this project ofinstalling a 55-56 Packard PS pump on a 56J. I did so before, long ago on another 56J, and it worked great, was smaller, and cleared the water-pump pulley better. But that pump was off a Nash, and had a 90 degree adapter coming off the pump itself, which plugged into the OEM 56J pump line perfectly. So, long story short, I am now trying to replicate that adapter. Any help would be appreciated. Thanks, Joe

Here is a guideline for the measuring standard flare sizes.http://www.gates.com/brochure.cfm?brochure=3109&location_id=3006
If the #6AC fitting fits then the tubing should be 3/8" and AC typically uses 45 degree. Whether you will find a 90 degree adapter to convert that pump inverted flare to something else might be an interesting search. There are straight adapters for inverted to regular SAE flare but didn't see any 90's other than pipe to flare. As you found, pipe size thread isn't the same. That adapter may have been a Stude special item. Checking with or taking the pump to a local hydraulic shop and seeing what they could come up with would probably be the easiest.
