thanks, Lawnmowerman [very inventive name] and Iansoady, mine sits high and rearwards. not the ideal solution, but it works ,after a fashion. sounds like trawling the autojumbles, and watching the bike mag adverts. I live in West Yorkshire by the way, and we have almost no classic bike traders anywhere near, so we are at the mercy of the postal system for almost anything for BSAs.Good forum , all same. enjoying the experience.
