What Chevy van body will fit on 82 4x4 K20 truck frame?

A Chevy van body from the late 1970s to early 1990s, specifically the G-Series vans (commonly referred to as the Chevy Van or GMC Vandura), can fit on an '82 K20 truck frame. These vans share a similar chassis design, making them compatible for body swaps. However, modifications may be necessary to ensure proper fitment and alignment with the truck's drivetrain and suspension components. Always consult with a professional or experienced builder for specific compatibility and modifications needed.
