I got them from Joe Duffy, got a lot of parts from him as I also had to replace the rear crown bearing but I think it was about €15 or thereabouts. Yes I fitted it myself, took about 10 minutes. Surprisingly enough I also fitted the rear crown and tapered bearings successfully also. If you need to do your's I still have one seal and washer as spares if you need to order one from them and cant wait for them to get it in.
