There is one bolt at the bottom of the dash that connects it to the side of the cowl (on each side of the dash). All the rest are at the top.
After removing the garnish mouldings, you will see several 5/16" hex head screws down in the defrost gutter space all across the top of the dash close to the windshield.
Of course, you will need to remove the two long philips head screws that hold the steering column bracket to the dash. Be sure to remove the bracket cover first so you dont damage the Fordomatic selector needle under that cover when removing the dash.
Make sure all your wiring, heater control cables, speedo cable and other stuff coming thru the firewall has been disconnected/removed before attempting to remove dashboard.
You may want to get a second person involved in holding the dashboard securely in place while you are trying to remove the last screw holding the dash in place, so that you don't strip out the hole at that last screw.
