Building a 1973–1987 Chevy or GMC Square Body?

Whether you’re building a 1973 C10, 1977 K10, 1980 C20, 1984 K20, 1986 C10, 1987 R10/V10, or another Chevy or GMC Square Body project, we can help you determine the right cab configuration for your build.

Rust Belt Offroad builds reproduction classic truck bodies right here in our Canfield, Ohio facility using fixture-built assembly, precision alignment and factory-style resistance spot welding.

The first-generation Chevrolet K5 Blazer was only produced from 1969 through 1972, but those four model years have become some of the most recognizable and desirable classic SUVs ever built.

At first glance, a 1969, 1970, 1971 and 1972 K5 Blazer can look very similar. Look a little closer, though, and there are important differences in grilles, trim, brakes, drivetrain choices and other details that matter when you’re buying, restoring or building one.

Why spend months repairing rust, hidden damage and decades of questionable bodywork when you can start with a better foundation? Rust Belt Offroad builds 1969–1972 K5 Blazer and GMC Jimmy bodies, plus 1967–1972 C10, K10, C20 and K20 replacement cabs, right here in Canfield, Ohio. Whether you’re building a stock restoration, restomod or full custom truck, starting with new steel can save time, reduce costly body repairs and get you closer to the finished build you actually want.

Many imported Chinese reproduction bodies can suffer from poor welds, out-of-square construction, diamonding, weak sheetmetal, bad fitment, orange peel paint, and incorrectly installed crush points. Learn why choosing quality construction can save time, money, and frustration on your restoration build.
