Kubota ROPS Clamp (Anti-vibe knob)

Kubota calls this a Clamp Rail Cover (p/n 53721-61533). It's used on the fold-down ROPS (Roll-Over Protection System) on my BX25D to clamp the ROPS so it doesn't vibrate during operation of the tractor. I've managed to break the OEM part twice and decided to design a (stronger) replacement part so I didn't have to make the hour-long round trip to my Kubota dealer (who keeps bankers' hours).

Misc. parts needed.
1 ea Hex-head cap screw (bolt), M10-1.25x40
Cyanoacrylate glue (optional)
