    A/C Vacuum Actuators (controls)

    The van's vacuum actuators are still operational but I worry that they may soon fail. Given that many old GM parts are still in production in the US, and that these are probably based on existing GM designs of the time, has anyone tried sourcing new ones?

    I bought these from the us for my hj, exact same diameter as original, mounting studs lined up, only difference the pipe for the vaccum hose pointed in the opposite direction which wasn’t an issue. Check out their catalogue, they have many other types.

    Thanks again @Oldolden. They are exactly what the doctor ordered.

    Here's how they are different

    You can see from the underside how the angle of the vacuum pipe connection was changed, because the bolts are on the opposite holes. I guess that means there is a similar part somewhere that is an exact fit. And be prepared to grind off a small portion of the bolt as sometimes it's too long.
