Diff Oil Leak after Service

[cjvrensb]

My ZE was in for service at the dealer I always go to, and the next few km's after the service, I noticed a leak from the Final gear oil filler bolt. I am about 280 km away form the dealer and cant just drive there quickly, so I phoned them, and was advised that the gasket was probably damaged upon installation.

Where can one buy a gasket like this, it is made of copper as informed by the dealer?
