You just make a delete plate that is flush with the firewall, bolt it in from inside the car, and have holes for the heater hoses and vacuum line to pass through. All that is under the dash has to be retained. You also have to make a path for the air to blow through because in stock form the air goes past the evap core then across the heater core. If you google something like a/c delete but still retain heat you should find pics etc.
