This ain't rocket science. 2 pieces of flat stock and a few minutes time with some simple tools will make the brackets. Drill three holes (1 for the mounting point, 1 for the chain to go thru, and one at the end of the slot). None of the dimensions are critical, you can drill both pieces at once of you want. Then use a hacksaw to connect the holes for the slot. Add paint if desired and bolt it on. If you have the drills and hacksaw the cost will be a few cents each. If you have some scrap steel, free.
