Hi Stuart,
That will be a very good idea if the PSSA members could have many recommendations for all the parker parts now the Parker shipyard is closed.
I had this problem, after my rudder was broken, Phil Milanes could not have the rudder blade drawing by the new shipyard which has bought the 335 mouldings.
You can find upholstry fabric in Paimpol or in Lézardrieux.
