Replacement rear window weatherstrip for 1964-1966 Plymouth Barracuda 2-door hardtop coupe models. Designed to seal and cushion the rear glass, the profile includes a trim groove to accept a lockstrip for secure trim retention. Made from durable EPDM-type rubber with OEM-style fit, it restores a watertight seal, reduces wind noise and vibration, and resists UV, ozone and shrinkage for long-lasting reliability and easy restoration projects.
Features:
  • Fitment: 1964-1966 Plymouth Barracuda 2-door Hardtop Coupe models (rear window).
  • OEM-style EPDM-type rubber construction resists UV, ozone and shrinkage for durability.
  • Includes trim groove to accept a lockstrip for secure trim retention and accurate fit.
  • Seals rear glass to prevent leaks, reduce wind noise and protect interior trim.
  • Straightforward replacement part ideal for restorations or maintenance of classic Barracudas.
Installation / Application:
  • Difficulty: 3/5
  • Estimated time: 1-2 hours
Suggested Tools:
  • Plastic trim removal tool
  • Flat screwdriver or pry tool (wrapped in tape to protect finish)
  • Lockstrip installation tool or small rubber mallet
  • Weatherstrip adhesive or butyl rope (optional)
  • Rubbing alcohol or cleaner and lint-free cloth
  • Spray bottle with soapy water (optional)
  • Gloves
Instructions:
  1. Carefully remove the interior trim and any retaining moulding to expose the old weatherstrip and lockstrip.
  2. Remove the old weatherstrip and lockstrip; clean the pinch weld and glass flange with rubbing alcohol to remove old adhesive and debris.
  3. Test-fit the new weatherstrip on the flange to confirm orientation and fit; trim the seal to length if necessary.
  4. If using adhesive or butyl, apply a thin bead to the pinch weld per manufacturer instructions; a small amount helps hold the seal during installation.
  5. Seat the weatherstrip onto the flange, working around the opening and pressing the bulb and base fully into place. Use soapy water to lubricate if needed.
  6. Install the lockstrip into the trim groove, beginning at one end and tapping gently with a rubber mallet or lockstrip tool until it fully engages and secures the seal.
  7. Reinstall any exterior/interior mouldings and trim, check glass positioning and adjust if required, then allow any adhesive to cure per adhesive instructions.
  8. Inspect for gaps and water-tightness; road-test at low speed to listen for wind noise and re-check fit after initial driving.
