Need help removing somethings

first look and see if there are nuts/studs in the engine bay around the heater motor,, on my early A there are 4 nuts on studs thru the fire wall holding the blower motor to the fire wall,,then there is a rod that looks like a J hook going from the bottom of the fresh air box you know the big door you open for fresh air,,,,that rod goes up in to the cowl area acts like a hook holding that end of the heater box up,,

so first disconnect the cables from your dash,,or disconect the hole cable assembly then do the wires to the blower motor,,mark them some day you may want to reinstall it all again,,,

then disconect all your heater hoses frok the fire wall and engine,,,unbolt the J hook rod from bottom of fresh air box,, it should fal out,,maybe some anti freeze in it becareful
