    Does anyone know what size the flared fitting is on the end of the cooler line that connects to the radiator?

    My radiator uses AN fittings so I want to screw an AN coupler fitting to the ends of the hardlines and then run hose to the fittings on the radiator. I'm guessing I need this fitting then.....https://www.summitracing.com/parts/rus-640600/overview/
