Finishing up the 4r100 swap in the race truck and I'm down to the cooler lines. Anyone know of an adaptor that will work to just screw the factory 5r lines right into the 4R? Or for someone who has done it what did you do for cooler lines. Eventually I'm going to run a cooler into the bed but don't have much time before worlds to get it done plus all the other things
