There will also be 3 10mm bolts at the bottom of the dash, one in each corner and one in the middle under the radio. You will also need to disconnect the E-brake handle's cable from the e-brake assembly, unplug the wiring harness in a number of places(It is bolted to the back of the dash and is installed with the dash from the factory then connected to the rest of the harness), disconnect the speedometer cable from the back of the speedo, remove the bolts that are under the speaker grilles (if any), disconnect the heater controls and their wiring/cables/vacuum harness, unplug all of the stuff on the steering column( ignition switch, turn signal switch, neutral safety switch, cruise control). You may wish to label with masking tape the connectors that go together with corresponding numbers so that you can distinguish what goes where. There are several sub harnesses that connect under the dash and it is important that they all go back to the right place ( exception being the bus box that uses interchangeable slots for a given type of circuit). That's all I can think of for now, good luck!
