F100 Wheel cylinder thread??

I'm running a set of early 50's ford f100 drums on the front of my project roadster. Doing the brake system and i cant get an answer from anyone on what fittings the wheel cylinders accept. I'm running braided lines (only thing i could get in a 20" length) with 3 AN fittins so i need a conversion fitting to the wheel cylinders.

 

the wheel cylinders have 3/8-24 threads

 

Try a 3/8s fine thread bolt ,if that is too small it will be 7/16thX 20 fine thread.
