On our high windshield cars, its easiest to remove drivers seat and the steering column clamp under the dash. Then you can lay on your back with your head jammed against the pedals and see well enough to get the wingnuts off and work the gauges out. I'm 6'-4 so I need all the elbow room I can get but a more compact person might not need as much room.

yes, you can remove the dash - the difficulty lies in the sort of fasteners you have. Stock AFAIK is 10mm bolt with phillips insert. I took a 10mm socket, ground the sides down so that it would fit into the dents, then drilled 2 holes right through at right angles and use a drill bit to slowly undo. Some people apparently have used the small angled screw driver. The biggest pain is the oil line - the rest have some play in them.
