91 Caprice Exhaust Manifold Ball Flange Adaptor

Hello! I am looking for this part that goes between the exhaust manifold and y-pipe on the passenger side of a 1991 Caprice 305.

Its that obscure part I cant really buy new, find at a local junkyard anymore or any one would usually even hang on to when swapping to headers. But I am really Hoping one of Y'all has a parts car or one kicking around that I can purchase.

Thank you in advance!

I believe that the part you are looking for Is part of the pipe

Thanks for the response!

On the drivers side you are correct. on the passenger side the manifold is flat and the y-pipe has a ball flange. This small piece goes in between and is all clamped together by the studs. I am looking for the small cast adaptor piece.

Here are some more pictures to try and help illustrate what I'm missing. The original photos show the circled in blue piece is what I am looking for.

Thanks again!

OK, it is a rounded cone doughnut. A real PITA part to get, and would cost way more than it justifies. Maybe you could get a muffler shop to make a standard flange and put a gasket between them.

Is that the crossover pipe seal? GM part number 14055405, they used them on a lot of models with the Chevy small block.  They're discontinued by GM but still around, evilbay has them.
