One thing to do in refurbing is to remove and polish the refractor pieces of metal that live just above the two lights that illuminate your speedo and tach/clock faces. They are made of metal and corrode over the life of the vehicle. Removing and polishing them is an easy way to get a bit more light onto the gauge faces. I've also placed some aluminum foil over severely corroded refractors to help them do their jobs when they were so corroded that they couldn't be brought back to life by polishing. Once you've got the gauges removed from the covers, find a friend or child with small hands in order to get inside the gauge console cavity and wipe out all the gunk that collects over the years. You'll be amazed at the improvement. The pictures in this folder show: 1: The positions of the 11 or so screws that fix the gauge cluster into the gauge console. It's necessary to remove these screws (carefully) in order to extract the speedo and tach/clock from the instrument console. The blue circuit foil that acts as a wiring harness for the gauges is also connected to the center warning (idiot) lights and so must be removed as well. 2: The light refractors (2) that exist for the tach/clock and speedo can become corroded as shown here. Simply cleaning will enhance the lights ability to illuminate your gauge faces.
