Another leak. Long story, but I'm missing the gasket that goes between the upper and lower parts of the housing. It has a 2 1/2" center hole, for the larger 261 bypass thermostat, and the off center bolt holes. Does anyone know where I can quickly find one? Maybe I have to make my own? I have found expensive complete gasket sets that seem to have one. Other vendors improperly offer just that gasket for the 235 housing with the smaller diameter thermostat. And they say it's for a 261😡
