Does anyone know if there is a mechanical t-stat sender that will fit? I'm having electrical problems with mine that might be more easily fixed by a change in system. Did that with the oil pressure gauge & can finally rely on the readings.

You must be referring to the sending unit for your temp guage. They are all electric and easily available. Thermostats don't have senders. They're mechanical valves that open as they warm up. They are manufactured to begin opening at specific temperatures. A 180 'stat will begin to open when the coolant temp reaches 180 degrees Fahrenheit. Same goes for 160 or 190 'stats.

A mechanical temperature gauge is available from various sources. It has a tube with fittings that screw into the block where the original electric sender was, this tube is permanently attached to the gauge. No electronics are involved except for lighting. They are available with different tube lengths so you can chose the best suited one for the application. The gauge face doesn't match the military pattern, so if you desire the original look, this solution won't work for you. If originality isn't an issue, you can easily acquire a mechanical gauge from NAPA, etc.
