I afraid your LBS is simply out of it's league. Your Normandy hub probably takes a standard 10x1 axle but needs very specific cones; there is such a variety of Normandy cones even for the same model that the only way to find replacement is to measure them, (then you can match them with up here
http://www.loosescrews.com/index.cgi...id=40431125762 for cones of the same size and thread) so it's a strong possibility they used the wrong cones (if they didn't save the old ones, your in a world of hurt).
