Just doing a cad drawing for my brake mounting bells and require the outside dimension of the hub flange(the part the studs go through ). Anyone know it off-hand,or got a hub handy they could measure for me .Also need to know the depth of the spigot/location part in the middle of the hub as I intend to incorporate a spacer into the bell but need to leave enough spigot to locate the wheel,anyone done this and know the maximum thickness of a bell in the middle/hub locating part.Any help would be much appreciated
