M50 T-stat housing question....

[RobPatt]

...I've got a slow persistant drip from my housing... Question is, is there one big gasket I need to seal the entire outer edge of the housing to the head? Right now I just have a small circular one for the thermostat, and another rectangular one that fits into a passage on the housing. Thanks. -Rob. (got new metal housing-current one is plastic, and new thermostat)

If you don't have the online parts database website saved to your favorites folder by now...it would be a good thing to do....it's invaluable for stuff like this.
