Plastimo skin fittings

[Fenders]

On the transom of my Bavaria32 (2004) there are 2 bilge drain outlets. Mine are very dirty and I have tried cleaning them but no joy.
So I have decided to replace them. Having tried 2 local chandlers and Ebay there seems to be aa shortage of these skin fittings.
I have been told that Plastimo have been bought out and that has interrupted normal production.
I have tried Aquafax but the only ones available are too large for my application.

Has anyone else had problems?
