Is there a more substantial exhaust manifold to exhaust pipe doughnut gasket for a 1938 six. It seems the original never seems to seal well. I didn't know if there might be a part number for a newer doughnut that I could purchase locally if there is an upgraded application.

I've found the OEM donuts to be long-lived and fit well as long as the mating surfaces are in proper alignment. But to see what else might be available, try a visit to your local muffler shop.

Thank you, I may have had an alignment problem, just not sure. I'll give the O.E.M. another try.

Make sure that you have the bracket that clamps the exhaust pipe to the bottom of the bell housing. They use two of the clutch pan bolt holes on the exhaust side to make the exhaust pipe firm and rock with the engine. Also good rear motor mounts will help prevent the pipe shaking loose,at the manifold connection.

Thank you
