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.
