Taking Autometer gauges apart

[CarlC]

I took the movement section from an Stewart Warner gauge years ago to do the same thing you are. I just cut the plastic outer housing away to get the movement. I found the easiest way to hold the movement in the factory gauge pod was to silicone it to the factory gauge face. Start the car, get it to operating temp/thermostat open, and re-install the needle according to the face temperature reading. The sweep angle of the new and old gauges must be the same.
