There's several things to know when your going to pull all of this stuff out. First, don't ever just haul on pieces and force them. If it's not coming then there is another screw somewhere, look for it. For those who don't know, there is a small push button on the bottom of the headlight switch behind the dash. Push it in and the headlight knob and shaft will slide out. There several screws holding the dash frame in the following places; Behind the black plastic switch cover next to the headlight switch. Unplug the back of it and underneath you will see 4 screws holding the lever in place and the aluminum plate the back lite is mounted on. Get all of the ones you can see by getting down by the floor and looking up. There's some above the gauge package, there's two underneath and behind of the ashtray. There's 4 bolts along the bottom edge of the dash frame that you wont see until the dash bezel is out, 5/16 heads. Three under the front bottom of the glovebox, pull it out and then 4 bolts to the left inside that cavity and two to the right as well as one way inside the right side that attaches to the cab wall. You have to stick your head in there and peek around the edge.
There are either 6 or 7 bolts along the top front edge of the dash under the windshield rubber gasket. Good luck with these if you are planning to keep the windshield as I cant see how you could pull them without removing the glass and gasket. If you run your finger tip along the rubber you can feel the slight bulges where they are behind the gasket. The speakers behind the door edges have a screw in the door frame facing the rear of the truck. The kick panel on the left has two screws up next to the e brake frame that are next to impossible to get to without the correct tools. If you do it right you should be left with the gauge package, the heat/air switches, and any other dash switches just hanging there, see the pics. Pull the gauge package forward off of the speedo cable head so you can move it to get the dash past it. Be careful not to pull too hard and snap the thin cable that moves the gear selector indicator.
