Water Temp Guage

["Gary" <vintage.racer@comcast.net>]

Hello.  I want to replace the electrical water temp guage in my TR4 with a
mechanical guage, preferably one with a guage face that reads in degrees
Fahrenheit.  Anyone already undertaken this?  If so, what brand (Stewart
Warner, Auto Meter, etc) and is the connection to the thermostat the same
thread size as the electric guage sending unit?  Thanks.
