Had good luck with the Gates shrinking clamps, I ordered them cheapest from Oreillys also I used the silicone hoses instead of rubber, seems to work fine but like Jerry & Tech mentioned on others instances you need a good bead on the radiiator & filler as silicone is slicker that rubber, only benifit is its shiny and lasts forever, but then again so does a rubber hose. For the bends I used steel mandrel bent bends (Speedway) with beads made onto them and then I beaded my own end when cut but I had to make a set of dies on my lathe, I then powder coated them with the silicone hoses, looks really clean to me. On my other care I used the stainless equivalant of Coolflex I purchased from Speedway also.
