As I have "Porsche 911 Sportomatic" as one of my saved searches on eBay, I was interested to see this pop up. Someone has reproduced the vacuum servo diaphragm in silicone.

The listing refers to a YouTube video on R&R of the vacuum servo using the repro diaphragm.

Is the maker and seller one of us? Has anyone else bought and installed one of these reproduction servo diaphragms? I'm not currently in need of one but this may prove useful in the future. I'd be interested to know if anyone else has bought and installed one and how it's worked out.
