James; Go to a Napa outlet and have them look it up in their Echlin-United book. That 6V starter relay is a pretty generic part that Chrysler used on a lot of their cars and which Autolite undoubtedly made for other brands, there should be an equivalent available. Once you have the number any auto parts store can cross reference it if you don't like Napa's price.
