74 Charger gear box pressure line fitting help

[Hijinx]

Does anyone know on the gear box the size of the fitting for the pressure side line? 3/8-NPT maybe?
Trying to connect the system below...

Are you asking what size wrench will fit on it? dumb question, I know, but if so I am happy to go out to the driveway and figure that out for you.

thread size... i think i have it figured out though... just bought a stock pressure hose and will convert the other end of it to -6an to fit the pump.
