Eric, mine is a 1942 Dodge. Some Chrysler used the same return spring 677446, but not 1936.

1937 C15, used 667673.

I wish I knew if any numbers interchanged. I don't know if the difference was number of coils. I believe after the war many went to a 2 cylinder setup and a totally different spring.
