72 Duster A/C evaporator

You need to remove the glovebox liner to gain access to the upper bolting and other items on top of the evaporator box; was not necessary on mine to remove the glovebox door as liner collapses. Need to unscrew the drain tube and disconnect the vacuum hoses on the side. Need to remove the bolt just above the kick panel which will give some flexibility to slightly pull the lower dash to give some clearance when removing box. Need to remove the A/C outlet vents box (2 nuts on bottom).

Note: heater box is separate and is not removed; at least not on my 1974.
