I'm using an overflow bottle from a Mitsubishi Montero but because the OEM mounting bracket was a huge I left it in the car. I needed to make a bracket that would work in a location that would work for me so I sketched a quick design of what I needed and cut it out of some 16ga metal that I had laying around. I made a couple of bends, welded it up, then drilled and inserted a few 1/4-20 nutserts into the grille.
