Notes:
Does not offer full coverage from the LH rocker panel to the RH rocker panel like a traditional 1-piece floor. Recommended to measure coverage area of the replacement floor and compare those measurements to the existing floor BEFORE the old floor is cut out of place. On all models except El Camino and Caballero there will be a minor modification needed at the rear of the transmission hump where it meets the under the rear seat floor section. The Grand-Am, Grand Prix, Lemans, Malibu, Monte Carlo, Regal and Supreme(Cutlass) have a slightly different shaped transmission tunnel in that section of the floor pan.
