Deuce LoverThe bezel has separated from the housing.That gauge(or at least all faces-except temp) are incorrect for your car.Its for 39 Std. Easier to get to it by pulling the speedo ,then reach in and undo the 3 nuts holding it in.Remove the temp unit before undoing the 3 nuts..3 screws secure it to the housing.
Here is a pic I pulled off the internet of what your gauges should be.
