I buy them from the M-B Classic Center, I'm sure I have the correct P/M buried some where in my files .

I looked OnLine and don't see it : https://www.pelicanparts.com/catalog/SuperCat/16308/MBZ_16308_EXHMIS_pg1.htm#item2

I know it's also available off brand, I know a guy in Pasadena who uses them in his indie muffler shop .

The thing is : they cannot break and so drop your exhaust like the plain rubber rings do occasionally .
