OK, so I did find an original 911 RSR exhaust bracket https://pbase.com/slidevalve911rsr/image/52910000 and another that I already had. The first bracket was "cut" at one time (top was chopped off!) https://pbase.com/slidevalve911rsr/image/52910012

At the time, I had no idea that the exhaust bracket https://pbase.com/image/53097259 I had in my hand was actually an original Porsche factory 911 RSR part and almost through it away! Can you believe it?! I later restored it to look just as 'good-as-new' and gave it https://pbase.com/slidevalve911rsr/image/53097210 away to my good friend Bernie Bushchen who will put it to good use.

If you go to Ernie Wilberg's Porsche 911R website, you can see in this photo https://pbase.com/911r/image/27290804 this very exhaust bracket https://pbase.com/slidevalve911rsr/image/52910007 installed in a 911 RSR and also here too https://pbase.com/slidevalve911rsr/image/55853300 in a factory Kremer RSR ; )

I often wonder how many of these very rare and NLA Porsche racing parts actually end up in the trash cans by those who unfortunately just "don't-know"...
