Hi, does anyone know of a good source for these bolts that are used for hanging the hydraulic lines from? I believe the book calls them 'shoulder nuts' but in French.. I've heard them called various names recently. I am specifically looking for some BVH specific items - for the centrifugal regulator, and the supports for the left brake caliper to secondary idle going past the block - one of these bolts needs a 40mm nut. I'm at the point of just using a joiner nut and studs if I can find the correct pitched thread. Cheers!
