Yeah, there was one long M6 or M8 bolt going all the way through the hub and bolting the peg on the non drive side. Not sure that's a fool proof way of doing it but I'm currently going to be running an Unbrako , longer than standard M6 going into my Echo hub with a top hat washer to reduce the peg hole down from 3/8" to 6mm. Think it may be asking for trouble though!
