They're not very long, about 1/2 inch? Not sure what the thread is, though. Mine are round headed screws not bolts. As I've got the gearbox exposed at the mo I could pop one out and measure it a bit later if no one knows. Bet it's a UNC or BA size.

OK - just measured one. Slightly over 1/4 inch thread length, it's a good fit in a "SAE 3/16 AF" die, which I think makes it a UNC thread but I'm not sure what thread size this equates to. Google wasn't too helpful but I'm sure someone here knows.

Thanks for that! Mines still fitted with the drum in place also an O/D to make getting the bolts in all the more fiddly
