Need Part Help

[1974carrera]

I'm trying to source the copper-plated M10 lock nuts that are used to attached the muffler to the turbo on my 930. Porsche indicates p/n 999.084.005.02 but shows none in the U.S. and some in Germany. PP shows this number is superceded, but not to what. In neither case can I tell if these are actually copper-plated M10 lock nuts. Anyone know a source and/or the correct part number? Here is a pic of the last four I have: Thanks,
