Hey guys! New here to the group, but I am in urgent need of some help. It appears that during a recent trip, the right rear nut on the rear axle of my GW250 came loose and fell off. I'm counting my lucky stars that it didn't result in a horrendous crash, but I'm not riding until this issue is fixed. I thought this would be a simple matter of simply going online and ordering them from a parts manufacturer, but I've received e-mails from two different companies stating that the rear axle nut is no longer being manufactured.
What am I to do? Is it possible I'm ordering the wrong part? I've included a photograph of the part that is missing on the chance that I am an idiot. Would it also be possible to simply go to a local department store and walk out with something serviceable?
