Strangely enough, I see nuts welded to the stationary part of the ROPS on my LX. The darn thing rattles and is VERY annoying when doing anything like quick direction changes, rough terrain, etc. I can't help but believe that nut was welded there for a thumbscrew or something to stop that rattle. Does anyone have the part number for that thumb screw? Looks like it's probably M8/1.25 but I haven't actually checked it with a bolt.
