I'd like to do my firewall but dont have the ching for a AC unit just now so it would be most helpful if I could see how you did yours. Thanks

Are you talking about the top lever on a factory A/C system? That is the one that controls inside/outside airflow, via a vacuum switch. All the way to the left is for A/C (pass side kick panel open for recirc, cowl vent closed) To the right is for heat (kick panel vent closed, cowl vent open for outside air) The other two levers operate cables.
