1964-1967 Flatline Barrier Complete Kit, Convertible

The 1964-1967 Flatline Barrier Complete Kit (Convertible) is a vehicle-specific thermal and acoustic insulation package custom-cut for first-generation GM A-body drop-tops. Because convertibles lack a solid steel roof structure, they suffer from much higher levels of wind buffeting, pavement heat, and exhaust drone.
This pre-cut kit eliminates the hassle of measuring and cutting universal material sheets by providing exact pieces tailored specifically around the unique interior packaging of 1964–1967 drop-tops (such as distinct rear seat support structures and convertible top hydraulic clearances).
Product Specifications & Coverage Areas

  • Complete Kit Inclusions: The full convertible bundle covers every main sheet-metal surface area of the cabin floor, doors, and rear cargo hold:
    • Full Interior Floor: Seals the transmission tunnel, front footwells, under-seat pans, and kick panels.
    • Doors & Inner Quarter Panels: Fits inside the inner door shells and rear side panel walls to eliminate hollow metallic echoes.
    • Full Trunk Floor: Isolates the flat trunk pan and drop-down tank areas to block rear axle gear whine and muffler resonance.

  • Material Properties: Features an ultra-lightweight, high-density acoustic damping layer backed by highly reflective aluminum foil. It utilizes a high-strength peel-and-stick adhesive backing that bonds permanently to clean metal.
  • Safety Compliance: Manufactured and certified to satisfy FMVSS 302 federal safety standards for automotive interior flammability protection.
Vehicle Application & Interchange

This direct-fit kit matches General Motors’ classic corporate mid-size A-Body Convertible platform blueprint, fitting:
  • Chevrolet: 1964–1967 Chevelle, Malibu, and Malibu SS.
