OK, I am missing a 6mm? left hand thread nut from the shift linkage on my 250 aftermarket rear sets (Sportisi).

I am in the Springs and tried Apex, Rocky Mountain, fastenal, 2 other shops, and a scooter place. I can't find one for the life of me!! I can't believe it is this hard?!?

Does anyone have an extra or know where I can get one before Round 7 tomorrow?
