David, the gauges will have to come out, but once the wires are out of the way it's easy to get at them. The glove box will be more of a pain than other things. When you do the big gauges, loosen the top hold down just a bit and then take the bottom one off and spin the gauge to get to the top one, saves the fingers, install the reverse way. Good time to replace the top of the dash, if yours is bad. I find a 1/4 inch drive socket and about 8 inches of extention make this a much easier job. Wayne
