Axle vent threads

[74 Bronco Billy]

I am trying to find out what the threads size is for my Dana 44 and Ford 9" vent tube. I am replacing them both with custom vents (deep water crossings ahead), and need the size to figure out where to buy a nipple to put in and then convert down to the fittings I am using from a kit. Is it 7/16-20 or is it NPT?
The threads on the old vent do not seam to be pipe thread.
Thanks, Forrest;D

I know mine was not a pipe thread, I can't remember what size it was for sure though. Do you have some fine thread bolts you can try to verify?

It's 7/16 x 20

no taper. a regular cap screw will fit.

I had some made a few years ago, I have a few left......
They are 7/16-20 X 1/8" female pipe, you can put whatever you want on them. As shown push-to-connect, barbed fitting, etc.
