Dimensions of the pilot shaft screw
 

Does anyone know the dimensions of the pilot shaft screw that goes on to hold the clutchbell on? Mine came loose and was lost to the track gods, so I need another. Just not sure what the size is.

just a regular M3 thread size (M3x0.5pitch)

i would at least use a cap-head screw though and not a button head...length can be anywhere from 4mm-16mm...any length in that ballpark will work.

And use a dab of blue loctite.
