Can you weld? or get a parts to a welder? I would purchase a local black pipe from a local hardware store. Buy 2 inch pipe or larger and 90 degree elbow. One long to reach over cars and short to go inside a larger pipe to make your "hinge" . Weld in another pipe or you can use 2 flat stock bars of metal on both sides to form a triangle gusset to give support to boom. The larger pipe (I am guessing 3 inch about 4 feet long) should be welded onto a flat stock that you can drill holes for mounting plate to bolt onto the garage wall. Once its all made up - you can fish the hose inside the pipes . Use the vacuum hose with lightweight string to pull through the pipe to create a pulling string to fish the hose inside of . Keep it simple - and cheap.
