For the live of god, I can not figure this out.

The fasteners that hold the seats down are M10 x 1.25, but the damn staybalizer bar (runs parallel to the trams tunnel & fastened by a single bolt, that seems to be integrated into the bar it's self) is a slightly larger fastener.

I've been to a few hardware stores, but I've turned up empty handed (weekend shift kids know about as much about hardware as I do)


Think Mazda might have used a M10.5x1.25 or an M11 (if they even make that size)

I tried various thread pitched M12 fasteners, but it won't thread.

Any help would cure this stroke I'm working on...
