What is the size of the flanged fitting on the cooler lines? I purchased the AN-6 x 1/4 NPT fittings and the 1/4 NPT fit in the Ron Davis aluminum radiator but the AN-6 was too big for the cooler line. Bought an AN-4 and that was too small?

Ford C4 Auto Trans Cooler Hard Lines | Stainless | 73-77 Ford Bronco

The stock cooler tines accept 1/2-20 thread to the Ron Davis 1/4 MPT. Like our part #F2610
