The Ford F-250 and F-350 Super Duty trucks have a dashboard that you can take completely out. There are only a couple of bolts to take out in the dash removal. Mostly, there are push-clips that hold the dash in place. These clips hold the dash securely, but they are very easy to get undone. All of the electrical connectors are push-tab connectors. Just push in on the sides and pull them away from the dash.
Insert the flat head screwdriver into the small notch on the bottom of the headlight and dimmer switch panel. Gently pry the bottom of the panel off. Move to the top of the panel where there is a retaining clip just to the left of the dimmer wheel. Undo the retaining clip and remove the panel. Pull off the two connectors by pressing in on the sides and pulling them away.
Place the U-shaped radio pull-out tools on either side of the radio. Insert them into the slots as far as they can go and put pressure on the insides of the radio by pulling the outer parts of the tools away from the radio. While doing this, pull the radio out with the tools. Unhook the electrical connector and the antenna from the radio and remove it completely from the dash.
Remove the two bolts that are inside the radio compartment, on the top of the compartment. These bolts are 7 millimetre and can be removed with a 7-millimeter socket and the ratchet.
Position the tilt wheel all the way back. Pull the dash out slightly. Pull the eight push-clips that are along the sides of the dash out and keep them in a safe place. Gently pull the dash straight out. Be very careful with the area around the steering wheel, as it is very thin and fragile. Be careful with the area around the passenger side airbag; there is a push-clip connector that you can pull off and a connector by the power point that you will need the flat head screwdriver to push in on the side of to be able to pull it off.
Remove the two bolts at the bottom of the instrument cluster. Remove the three push-clip pins at the top of the cluster by hand. Slide the cluster out enough to get your hand in the back. Pull off the wiring harnesses on the back of the instrument cluster by pushing in on the sides and pulling. Pull the instrument cluster out.
Keep all clips and bolts separated. You can tape each group of clips or bolts to a clipboard with masking tape and write where they came from on the tape. This will make reinstallation much easier.
Be sure to have the vehicle off and the battery unhooked. There is a good possibility that you will fry your vehicle's computer when taking the dash off if the wires and leads inside the dash are hot.
