Guys, I'm running a Champion EC369 radiator and will be retaining that for my 5.3/4L60E swap. Can I reuse the lines from the TH350? I would prefer to go that route if possible. My second choice would be to go with AN fittings and line. I know they make the adapters for the transmission side but not sure what I need to adapt the cooler side. According to Champion, the fittings in the radiator are 1/2" 20 straight thread G 1/4".
