37 120 automatic choke gasket

Does anyone know of a source for the gasket between the automatic choke cup and exhaust manifold for a 37 120? It is no longer included in a manifold gasket set and every one I have made has blown out from heat and pressure. It is a rolled copper sheet metal ring 2" in diameter. 1/8" cross section.
