Rear 1/4 Window Hinge.

The OE MATCH Rear 1/4 Window Hinge is a replacement component designed for Porsche 356 A, B and C Coupe models. Manufactured to provide an OE-style fit, appearance and functionality, this rear quarter window hinge helps restore the smooth operation and secure positioning of the vehicle's opening rear side windows.


Fits:
  • Porsche 356 A COUPE
  • Porsche 356 B / C COUPE -REUTTER-

Diagram Ref No 13

Available in left-hand and right-hand versions, the hinge forms part of the rear quarter window opening and retaining mechanism, allowing the window to be opened for ventilation and held securely in position.

Ideal for replacing worn, damaged, corroded or missing original hinges, this component is particularly suitable for classic Porsche restoration projects and routine window mechanism repairs.

What This Product Does:
The rear quarter window hinge forms part of the mechanism that allows the rear side window to open and close while maintaining secure positioning.

Its key functions include:

  • Window Operation: Allows the rear quarter window to be opened and closed for ventilation.
  • Secure Window Positioning: Helps retain the rear quarter window in its intended open or closed position.
  • Ventilation Control: Enables occupants to regulate airflow inside the vehicle through the opening rear side window.
  • Stable Window Support: Helps maintain correct window positioning and reduces unwanted movement or rattling.
  • OE-Style Appearance: Maintains the original design and appearance of the Porsche 356 rear quarter window mechanism.
  • Reliable Functionality: Supports smooth and consistent operation of the opening window assembly.

Symptoms Of Wear Or Failure:
Over time, regular use, ageing, vibration and exposure to moisture can cause rear quarter window hinges to deteriorate. Common signs include:

  • Loose or Rattling Rear Quarter Window: A worn hinge may allow excessive movement, causing rattling or vibration while driving.
  • Difficulty Opening or Closing the Window: Worn, damaged or seized hinge components can make window operation stiff or uneven.
  • Window Not Staying Securely Positioned: A deteriorated hinge mechanism may struggle to retain the window in its intended position.
  • Visible Corrosion or Rust: Moisture exposure can cause corrosion, weakening the mechanism and affecting its operation.
  • Broken or Damaged Hinge Components: Cracks, deformation or physical damage can prevent the hinge from functioning correctly.
  • Excessive Movement or Play: Wear within the hinge mechanism may cause the rear quarter window to feel loose or unstable.
  • Poor Window Alignment: A damaged hinge can contribute to incorrect window positioning, potentially affecting the fit against surrounding seals.
  • Worn or Deteriorated Appearance: Scratched, corroded or damaged components can detract from the original appearance of the vehicle's interior and window assembly.

Why Replacement Matters:
  • Replacing a worn or damaged rear quarter window hinge is an important part of maintaining the functionality, comfort and original appearance of your classic Porsche 356.
  • A properly functioning hinge helps ensure the rear quarter window can be opened and closed smoothly while remaining securely positioned. This provides convenient cabin ventilation and helps prevent unwanted movement or rattling while driving.
  • Damaged or excessively worn hinges may cause poor window alignment, difficulty operating the window or additional stress on surrounding fittings. Replacing a faulty hinge can help prevent further deterioration of the window mechanism and associated components.
  • Correct window positioning is also important for maintaining proper contact with the surrounding seals, helping reduce the risk of wind noise and water ingress when the window is closed.
  • For classic Porsche restoration projects, replacing deteriorated hinges with OE-style components helps maintain the vehicle's authentic appearance and original functionality.
  • The OE MATCH Rear 1/4 Window Hinge offers a practical replacement solution for restoring dependable window operation and preserving the quality of your Porsche 356.
