Both cooling tubes are now cut to fit and installed in the tub. DuBro brass barbs are soldered on each end and tubes are carefully bent to the angles I want. Using the long piece of brass tubing to drill the holes is the best method I have found for giving a clean and tight fit that will not leak once tub is sealed. Also with running the tubes flat on the bottom, once the inside of the radio box gets sealed with West Systems the tube mounting becomes very solid being coated with epoxy along the radio box flooring.
