Compatible with 1967-1972 Chevrolet/GMC Truck, Blazer/Jimmy & Suburban

These speaker assemblies are designed to fit exactly where your original mono speaker came out. Each set is mounted on a custom plate sized and shaped similar to the original unit. A special bracket is added to make installation with original hardware easy. What you get is quality stereo sound with the benefit of not having to cut-up your truck to mount speakers. Upgraded assemblies use high quality KENWOOD speakers.
