Not sure which bolt you mean. The one that holds the lever to the perch is 5 x 0.8, a very common thread. You need 21 mm of length not counting the head. The Campy bolt is threaded all the way to the head but there could be some unthreaded section, not sure how much, maybe 5 to 8 mm. The head is 9 mm in diameter.
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.
