Decided to ship today. Processed incorrectly at the factory. One side is always upside down. Will not fit both studs. One side is small, the other just right. Flip it over and you get the same thing just by switching sides. Visibly damaged surface, then painted over. Such poor quality from AC Delco has never been. Even if it was the new guy at work, what could kill you if you fail should only be of the highest quality and never walk out the door. Something to say about buying parts personally I think.
