The Dr Tuba generic strut bladders are a saviour especially if the originals aren't available. It is a basic strut shape that you can add the correct valve too, building up a new one.
Measure the length of bladder you need and if not exact, go one bigger (Never smaller). You may be able to use your existing valve by sticking it on with StormSure Glue or, for ease, pick the Dr Tuba replacement valve you need and simply make a hole in the blank and stick iton
