Thanks Randy!

Drew, I donít think they are NpT threadsÖ.

The dozen or so c6s Iíve rebuilt were npt. Maybe Shelby cars used something different?
My Galaxie and F100 both run full roller c6s I built. Both run AN hose, I used 1/8npt x -6 with no issue.

Check the one you get from Randy, curious about it.
Thanks
All of the Shelby auto transmissions and fittings were the same as the equivalent regular Mustang .

On a C6 the rear one has a 90 degree fitting like that while the front one is straight and just adapts the screw thread on the case to reverse flare thread found on the fitting.


Yes on late 68 and newer. Not 67- most 68

Might be just to have something to use look up "o-ring boss fittings" or "SAE o-ring boss fittings" in industrial supply company catalogs.  They are common in high pressure hydraulic systems with adapters to almost anything you can imagine. There also British and metric versions available.

These came from a '67 390GT that I parted out. I checked thread pitch with my Snap On pitch gage. It shows 18 TPI fits perfectly. I tried a Morse 9/16" X 18 NF die and it fits perfectly on both.
