Ok, first thing is to get the dash pad and glove box removed. Be very careful not to rip the ducts loose from the dash pad.
Once those are gone you have to remove the heater/defrost and a/c ducting (items 1,2, and3)
May seem a little confusing, but stay with me. Duct 3 fastens to the heater box with 2 screws and to duct 2 with 1 screw and then slides down from under a clamp strip. With it removed, you can work on duct 2. It has a screw through the top of the metal dash holding it up (just above the center).
With it removed, duct 1 can be freed from below the column and wiggled out of the way.
The last photo is the view with all ducting removed.
