1971 Chevy C10 Vortec SWB

When Chevrolet introduced the new GMT400 pickup body style in 1988, one of its standout features was the sleek, aerodynamic stepside bed. This design, made primarily of fiberglass, was a departure from the squared-off look of older generations, offering a modern and sporty appearance that gained instant popularity.

Custom fabricators quickly saw the potential to merge this new aesthetic with the classic lines of older Chevy pickups. Over the next couple of decades, it became a common trend to retrofit the GMT400-style stepside bed onto older models, such as those from the 1973–1987 “Square Body” era. This practice created a unique “restomod” effect—a blend of the rugged, traditional look of vintage trucks with the sleek modernity of the newer bed design.

These hybrids became a symbol of personal customization, appealing to enthusiasts who wanted the best of both worlds: the charm and durability of classic Chevy trucks, combined with the style and innovation of newer generations. This trend is still appreciated in custom truck communities today for its creativity and nostalgic appeal.
