For 2-door hardtops and convertibles, these rear roll-up quarter window seals measure 16-1/2" long and are sold as a pair. Designed specifically for 1968-1972 Buick, Chevrolet, Oldsmobile, and Pontiac models, as well as select 1969-1970 Cadillac and 1971-1972 Chevrolet Monte Carlo cars, these seals ensure a snug fit and reliable performance. Crafted by Metro Moulded Parts, they are made from advanced rubber compounds that resist sunlight, ozone, and chemicals, ensuring long-lasting durability.
