Classic Auto Air

Looked at the water valve and the instructions yesterday. It looks like there should be a bracket, but no mention of one in the instructions. It appears that they just want the valve hanging loose. Another dumb idea as I couldn't find anything that looked like a bracket for it. One more to fabricate...

Does anybody have experience making AC lines (tube, not hose) and have the tools for the ends? Preferably in California. We have a local shop that can do the job, but they are EXPENSIVE. CAA didn't send all the right fittings anyway...
