    Continuing these AC questions going around. I’ve just gotten the Original Air AC system installed on my camaro and I’m only getting air to the floor. I’m assuming it’s going to be a vacuum issue. Anyone have a diagram for an 80 Z? I know I’m missing the vacuum reservoir ball that mounts to the firewall

    Do you have a vacuum source running to the interior of the car.
    It's a small line coming through the firewall to the passenger side of the distributor and is normally connected to the vacuum reservoir.

    I dropped the car off at the muffler shop and won’t have it until tomorrow. The vacuum reservoir is missing though.

    Will any GM reservoir ball work or does it need to be ‘80 camaro specific? The ones at advanced and auto zone look the same

    As far as I know... Any vacuum reservoir will work.
    To have the proper size vacuum port connections, I would use the one you pictured.
    They are fairly inexpensive too.
