It's probably easiest to take out the whole dash, but I did it with mine in. My way wasn't fun by any means, but if I can do it...
Remove gauges, ashtray assembly, and glove box liner, then you can get a look at all the speed nuts that need to come out. There are also some along the front of the pad that are easy to get at, and a couple of screws on either end of the pad that you get at from the outside. You need a 3/8" small screwdriver socket type of tool, and also a short 3/8" wrench to get the front 2 corners.
