Plastic grommets that fit in the RH battery apron and LH front fender apron where the headlight wiring harness routes.
These are exactly like the original - not a generic replacement.
They protect the wiring harness from the metal edge of the fender apron.
These grommets are almost always missing or cracked.
Originally installed on all 1965 and 1966 Mustangs.
Sold as a pair.
