I've got one that I installed then took right off. It hasn't been on a running engine but I did smear it with the high temp orange silicone. I'd take $20 shipped for it.
I tried one, it spaced the puck far enough away it would not seal right, and it leaked to boot. Trash. I would rather have a leak, since it is not hurting anything after the turbo. Use copper RTV if you need to.
I ALWAYS USE ORANGE RTV FOR A GASKET, I DIDNT EVEN KNOW THAT A GASKET WAS AVAIL. FOR THE DOWN PIPE, HECK, I EVEN USE SILICONE FOR THE PASS. HEADER INTO THE TURBO.. JUST MY TWO CENTS.
Hey Al, I'm looking for it but not having any luck. I'll keep trying but my father-in-law sanded down the end of my Dp and exhaust housing where it was flush. Didn't need it after that but didn't want to throw it away as it hasn't been used. Can't say if it works (since I didn't use it) or not but you could try the sanding method then a little orane or copper RTV. I'll keep looking.
