"The Silverado, Cheyenne, Custom Deluxe, and Scottsdale trims were available trims from 1977-1979. Another new grille design entered the scene for these model years. It's easy to differentiate these grilles from the rest as they have fewer vertical dividers and one less horizontal divider. Early 1977 pickups featured low-back bucket seats, while later models had high-back bucket seats. An inside hood release was an optional feature."
