The Hellwig Frame FX kit for 1964–1967 GM A-Body (2-door) boxes and stiffens the factory chassis with a custom-fit set of pre-formed panels. The kit supplies 14 steel panels that reinforce weak areas of the frame rails, add an extra body mount to secure the floor pan, and include a transmission crossmember mount to support multiple drivetrain configurations. It simplifies the chassis-boxing process while improving chassis strength, handling and ride quality.
