a/c heat box removal on 74

daliant said
There are 5 nuts on the firewall under the hood, inside the car there is a brace that bolts to the ac/heater box behind the glove box. There are two nuts that hold the controls to the dash that are a pain to get to, or disconnect the cables and vacuum lines from the box just make note of where they go before disconnecting or take pictures. Be carefull it weighs about 30 pounds. Good luck.

There is one more bolt that joins the two...remove heater box first and it will be easier...on mine there is a hook inside the fresh air intake on the passenger side which hooks it to the cowl up top. I did remove the two cables and pulled the vacuum lines off....they each have a color trace line on them...like before mentioned write them down and draw a picture if need be..8)
