I made mine from 1/2" diameter aluminum rod I bought at Home Depot. I drilled & tapped both ends. Bent the rods in a vise using aluminum sheet stock for protection from the vise jaws and then polished them. They really shine nice. I used some welding rod to mock up the length so I got it right on the 1st try. I'm using stainless button head cap screws on the radiator end with a couple of washers for attachment.
