That person is me and yes I know the difference between A/C and non A/C kick panels and yes there is no need to remove the heater box. But do what you have to do... Have you detached the lever arm from the vaccum pump to the flapper door on the kick panel? The pump is bolted to the body of the car with two 3/8 bolts. It can be removed after the kick panel comes out. If still attached via the actuator arm then the kick panel wont come out. Otherwise the kick panel can be cojoled, coaxed, manouvered, whatever... out.
