Yes Neill, that's spot on mate.
FYI, I replaced my A1 with a kit this time last year and forgot (and still can't rember -oldtimersdisease

) the kit probably did come with a stopper for the left front. If so, mine only lasted less than one year and if that is the case, perhaps anyone else who have replaced their A1, should look at that little bu#ger of a stopper themselves. Like Neill says, the Triumph stoppers are of high quality and perhaps, and it looks this way, other stoppers are just inferior quality which leads to the probs I and others have experienced.
Also FYI, I just ordered 4 new rubbers stoppers from my dealer just to firstly, replace the left front with a similar stopper to the rest and secondly, to have spares knowing how important they are.
