These are the brackets that go between the forward surface of the core support and the inside of the headlight buckets. For 1971 and 1972 GTO and Lemans with the Endura bumper option.
These were originally rusty and pitted, they have been sandblasted, primed with epoxy primer and painted but still show signs of pitting. Would be okay to use on a driver-quality care but probably not for a show-quality car.
$20 for the pair plus $6 shipping to the 48 states.
