The original factory correct radiator cap that GM used on all 1982-1987 G-bodies did not have ears (tabs) on the cap. What made it unique from all previous AC Delco radiator caps and later AC Delco radiator caps, is that the source who made them for AC put the words “MADE IN ENGLAND” on the cap.
These original radiator caps have been cleaned and are in near mint condition. Even if you find one with the original AC Delco part number, it may have a later version AC Delco radiator cap in the box.
Another nice finishing touch for any correct under-the-hood restoration. Fits any 1978-1988 G-Body car.
Perfect for any restoration project!
