This is a tight fit but you do not have to remove the ignition switch or the speaker grill to remove the gauges. Three or four small nuts hold the gauges to the dash. A big comfort when I did this was a cushion for my back to cover the brake & clutch pedals as I was upside down under the dash. Another aid was a flexable extension for my small ratchet. Tag/mark/make a diagram of your wires when you remove them for easy reassembly.
