Jarvis, I have one in my Model A Ford. It is just a standard thermostat of the temp you require, tack welded into a piece of stainless tube that you can push up the hose. Make sure that the sensor end of the thermostat points toward the hot end of the hose. Would be easy to make one yourself.
Regards, Richard.
