While driving the Cobra the other night my SMITHS water temp gauge suddenly gave up the ghost with only 2700 miles.  It's a mechanical gauge and I've been tapping it, and have looked for kinks and wiggled it in the engine compartment.  It won't go past 60 degrees celsius, but I have confirmed the thermostat is working correctly.  I've read that these SMITHS gauges are prone to early failure.  I can get a new unit, but I'm concerned with being able to install it.  Does anybody have a good method on how to access it and what must be removed in order to do so?  Not sure if removing a seat will help as this gauge is right in the top center of the cluster being the street layout. Any help or advice would be useful as I haven't messed with a dash or instrumentation in a Cobra before.
