If it is and has snapped, what sort of condition is the actual bearing race in? Are there any marks on it, if so the best thing is just a new headset. But otherwise you can put new bearings (With 1 extra and plenty of new grease) Onto the race without a cage. All you need to do is measure one of the bearings and let me know the size. that way I can bring you them tomorrow!
