IF you want to do it more like factory did, they have, at least at times, used a “long” tubing nut at the transmission end of the line. Still the same wrench size but hex is appx 3 times “taller,” I would assume to make it easier to wrench on in the tunnel confines. More of a luxury than necessity and if bending your own lines they may present a problem to get a tight bend and enough tube to flare but they’re kind of nice.
5/16" is the size of the tubing. The inverted flare nuts that fit that diameter tube are 1/2-20 thread. Note that the the adapter fittings that screw into the aluminum trans case have male straight thread that seals with a crush washer and female 1/2-20 inverted flare threads that the tube nuts thread into.

Yes, I can see those nuts on the trans, and I suppose the washer is only good for just one tightening ? thanks for the info Joe

I wouldn’t be surprised to learn that technically the copper sealing washers are supposed to be one time use. In the real world, as long as they are in good condition with clean sealing surfaces I have never had problems with them leaking.
Don’t use pipe thread fittings in the case. More times than not the case will crack.
If you decide to use the factory long style flare nuts, be sure to pack the inside of the nut with antiseize. Those long nuts have much more room to fill up with crud, and are more difficult to break loose from the steel line once the environmental loctite sets in.
