LT1 Camaro, not sure on the year, IIRC it was a '96. They seemed to fit better when I flipped them upside down. Trimmed 1/4" off the edge closest to the g-body radiator plate and made two angle brackets and they bolted right in. Bottom has three tabs that grasp the core support. There are no LS1 cars in our local pick your part so these had to do. They pull a paper towel up to the grille when turned on so they should flow enough cfm to cool good.
