Each gauge has a built in stainless steel "Stem" affixed to and through the gauge's back cover; giving it superior strength against stress and vibration.  Surrounding the stem is a clear rubber washer that aids in the gauge maintaining its position when pulled against the beauty ring. The new stainless steel beauty ring incorporates a "Barrel" that accepts the gauge's stem.  Both pieces are affixed (pulled together) with a stainless socket-head screw and 2" mounting bar from behind -- giving the gauge absolute maximum security against separation from its mounting and the vehicle.  This mounting system is impervious to both weather and temperature and will never wear out or need to be replaced ... ever.

And, each bolt on unit can now be run with or without the beauty ring, depending on the users design preference.

The Stem and Barrel^TM system also makes chores like changing the battery or thermometer calibration a snap; giving easy access to the gauges internals.  The system can be taken apart or put together in seconds.
