For the Gauges, pull out the two torx screws underneath the top of the dash, then just pull. They are metal retaining clips so just yank evenly, you're not going to break anything. Then remove the four retaining scews to your dash pod and pull out the two wiring harnesses in the back. (i suggest using magnetized screwdrivers b/c you don't want to drop those screws behind that console..For the needles, use that puller or a fork (works like a charm still) and they will go flying so heads up. Peel off the old 3m backing with a utility knife and get all the glue off, carefully align, then dry and install.

AC panel - I kinda cheated on mine, by not taking the plastic bezel completely off since i couldn't get one of the radio wiring harnesses off. But just pull out the two torx screws under the radio (in the plastic bezel) and use the stereo removal keys. (This is with basic audio, if you have Mach 460/1000 I'm not exactly sure). Stereo keys on the cd player as well. Pull of the plastic bezel with equal force and voila. Peel the 3m backing off the AC with utility knife carefully and make sure to get all the glue off.
