Questions: replacing thermostat on my CJ3A; I have ordered replacement thermostat and gasket. However, when I removed housing, old thermostat had corroded apart and there was some kind of liner inside the housing. I do not see this part offered; it looks like it is needed to hold thermostat in housing. Pease advise. Thanks!
