I made a bracket out of angle aluminium that mimic's the original. I pounded the edges at each end flat with a hammer, then used a file to smooth it out. There is about 2mm on each side of the washer that makes contact and with a small drop of thread locker for good measure, the nut should not back off.
and thats A 31?? I have an odessey extreme 31 and it not a good fit, I made my own munted to exisiting bracket and an aluminum odessey holder for up top. Ill post when done
