904 cooler lines has female fittings

[Confusedcuda]

Went to install my new transmission cooler lines from Inline tube and the line that goes on the driver side of the radiator matched up and installed perfect. Went to put on the passenger side of radiator line and noticed it had female fittings on both ends. My fittings on my radiator and transmission require male fittings. Supposed to be the correct lines for a 67-68 Plymouth barracuda 318 with 904. Does anybody know what size/kind of fittings to use to make this work. i would need 2 male to male fittings on both ends of line. Thanks

This is the typical transmission cooler fitting found on the bottom tank of the radiator.
5/16" flare x 1/8" NPT

so I probably need a 5/16 male to 5/16 male flare coupling?
