Can anyone give me the spec for C10 3spd gearbox studs. Lengths, threads, lengths of threaded sections and any other info. A couple of studs were sheared in the casing when I got the bike. Can't source replacements so want to get some made up before I take the covers off the box. Bike is on the road so don't want to "open the box" before I've got the required bits to put it back together. Cheers, Rick.
