Mark, are you including the bolt on the expander plug in your statement about no left-hand threads? I know for a fact that at least some of the SunTour expander bolts were in fact left-hand thread. This is from bitter experience as I ruined a set of SunTour barcons trying to remove them while not realizing they were left-hand.

BTW, why would SunTour use left-hand thread there? On some components (fixed cups, pedal axles) it makes sense, but what possible purpose could a left-thread serve on an expander bolt?

There are no left-hand threads on a Suntour or a Campy.

Get back to me if you mean the bolt that expands the plug inside the handlebar, I can measure it for you. No standard bolt would work there unless you can drill it hollow and then broach it to take an allen wrench - usually a job for a machine shop.
