I have a 1995 Miraphone S186 that has plastic components attaching the linkages to the valves.  I have already replaced one of these plastic pieces and have cracks in all the others. Does anyone have an idea how to replace these components with something more durable?  I haven't heard back from Miraphone with a solution.  I appreciate anyones help.  Thanks.
