    Many used items in our pictures have been cleaned and/or bead blasted prior to being photographed to show condition and detail. 

    The item you receive, in most circumstances, will be pulled from the donor car and shipped to you without being cleaned. 

    We do not retake pictures each time a used item sells. Pictures are a good indicator of what you will receive, but not all used parts age the same. On high dollar parts, email us and we can send a few pictures of the actual part available.

    "Core" Items:
     If we use the word "Core" in the title of the product, the item has been deemed rebuildable, but has not been rebuilt.  The item you receive, in most circumstances, will be pulled from the donor car and shipped to you without being cleaned.

    Mounts on the rear of the intake manifold, it must be a 1967 or possibly a 1966 "S" intake manifold. There are no mounting provisions on 1968 or later factory cast iron intake manifolds. This valve has two equal sized vacuum hose fittings in addition to the steel line going to an intake manifold vacuum source. Due to the age of these valves, we cannot guarantee that they will work. Consider this valve non-functional.

    Ford part number C6AE-E or C6AZ-9B289-C. 1967 California emissions only.
