If I recall correctly there are 6 screws that hold the dash on. One on each side, which you found. Two on the bottom of the dash that attach to the metal frame work. And finally there are two nuts inside the engine compartment. One is hard to get to because the windshield wiper motor and mechanism is in the way, the other is beside the outside air intake vent. You have to remove the plastic cowl to access the nuts. You have to remove the instrument cluster first, it sounds like you've done this. The plastic part that surrounds the cluster has screws behind the light switch and a couple other blanks or switches. When you remove the dash you'll be able to access the boxes. The boxes are held together by clips that pop on and off. They have holes in the top and bottom that act as hinges for the air flow directing panels.
