I have bought a new thermostat for my Super 85. It looks as on following picture. I think I also need a gasket to it, which should be of the same shape like in the lower part of the picture

I cant find any on ebay as well as in local shops, but it is possible it fits from other Fiat engines. Do you have any idea which type should I be looking for or where to buy this gasket, OR what could I made it from?
