Maybe use for a cooler now and then lol
Great minds think a like
I wouldn't heat the plastic, it will likely ruin it's integrity. See if yours fits, if not, go to home depot or lowes and buy two sticks(roughly 2-3 feet long each) of the 1/8" x ~2" aluminum and cut, drill, and install. After install, I took some newspaper and masket the bracket off and sprayed it with some rustoleum rattle can paint to cover the screws, rivets, scratched parts, etc. that I mentioned before so it wouldn't rust again. No other issues so far. They are really nice, and you can remove them in about 5 seconds if needed.
