Guys, what is the application for 513 & 514 horns? They are dated 4-B-1 and 4-C-2; I am assuming that is 1964. I took them off my '63 Corvette and replaced them with the correct horns after they got dinged by the judges at an NCRS chapter meet.

Note that all those usages shown in the parts book are SERVICE applications, not PRODUCTION applications; it means that they'll work as "functional replacements" and bolt on without major modifications. You need a Delco catalog to identify the production applications. :)
Thanks to both Philip and John.
