Pull the windshield out and then you will find a row of screws across the top of the dash frame hidden under the rubber window gasket. The other two dash bolts are behind the kick panels.
Make sure all the heater hoses and wiring is disconnected before pulling the dash frame out.
You can pull the heater box out by removing the bolts around the outside of the blower motor in the engine compartment along with a couple other bolts on the firewall.
Probably need to disconnect the parking brake handle from the bottom of the dash frame IIRC.
