Looking for weather cap for Zumo 660

[farmer998]

In need of a new plastic weather cap for the motorcycle mount for Zumo 660.  It blew off and landed in heavy traffic yesterday as I was acceleration from a stop light.  I would have stopped but traffic and highway layout made it impossible.  The part has been discontinued.  Looking to see if anyone has one to spare.  If anyone has an alternative please let me know.
Thanks  Randy

I have a Zumo 665.  I't immersible to some military standard.  So I'm not clear what you need.  I have mounted mine so it's behind the tipped shield - rain doesn't get to it anyway.  I did glue a sunshield on it to help with the brightness in the sunlight.
