Had mine made. Went to a hose and fitting shop and had the large pieces created ($25) including a lip to help hose sealing, I then marke the positions of the TB heater tubes and had a A/C shop solder in new TB heater tubes ($20) and finally I took the assembly to a plating shop and had the new assembly yellow Cadmium plated (if you can find a plating shop that does black Cadmium plating, you won't have to paint you tube assembly black when you get it back) ($15). The only thing I didn't do, was have the two large tubes soldered together.
