    I’m looking for a 2-piece flat distributor cap for a 1931 Pierce Model 42. If you have an extra lying around, let me know!


    I have a used one from a 1935 8 cyclinder. The numbers on the cap are not correct for the firing order, but it works fine.


    A 1935 8 cylinder cap will not work on a ’31 Model 42. The ’31 distributor is Delco 668E and the cap is two piece with a single thumb screw that holds the two pieces together. The ’35 cap is smaller diameter. The Delco cap for ’29-’31 Studebaker President will fit. It is one piece and looks “modern”” compared to the Pierce cap. I’ve attached a photo of the Pierce cap.



    Hemmings is a good source for ignition parts.Check out the services

    offered section,under distributors.March had 6 entries.2 specifically

    noted they dealt in caps.The others remanufacture and tune distributors

    and may suggest sources that will have the part you need.Our parts and

    services section connected to this site is usually very helpful.To

    be able to use this resource is worth the Society dues.I don’t know

    of any other old car club with such extensive,organized data that

    will give you a parts number and a current source where it is


    I’ve been looking for a bracket that the top rests on,for my Model A

    Ford Phaeton.None of the various Parts House catalogs list it.After

    8 years,a fellow owner gave me a source.My P.A.s don’t wait that long.
