Top Carb gasket 1.5/1.6

Hi, I am looking for the gasket/rubber seal that goes between the air filter element and carb on my 1.5 GX.

I believe the 1.6 carb engine with the pierburg 2E2 uses the same air filter element so guessing its the same seal.

Do anyone have a good unused one laying around or know where I can get one new 

Thanks Luke
