Anyone who owns one knows how the panel flexes with no support. Pain in the neck when you're trying to clean. Had some hardware,carriage bolts and tabs of metal and made these. The holes are already in the body. It's a little tight getting the nut underneath there is access from the side, you might have to take the panel off I squeezed my hand in there.There's a nut underneath the tab at the top so you can screw it in then position the tab. Nice and firm now. Not the prettiest looking but nobody sees it. Anybody with a 2021 did BRP fix this?
