Product Information
Plastic base gasket for quarter window assembly.
A precision-moulded plastic base gasket that sits between the quarter-window hinge/base and the body. It reproduces the OE profile to seal the mounting footprint, protect paint, and set the correct standoff so the glass and latch align properly.
Sold each, 2 required.

Fits:
Porsche 911/912 1965 - 1977

Diagram ref no 18

• Application: Rear quarter window assembly (pop-out/hinged type) – Porsche 911
• Side-agnostic; sold each (order two if renewing both sides)

Function:
• Seals the hinge/base to the body to prevent water and dust ingress
• Protects paintwork from abrasion and crush marks
• Helps maintain correct window alignment, closing pressure, and reduced wind noise

Over time, the original quarter window base gaskets can harden, flatten, or shrink due to age, UV exposure, and temperature changes. This can cause water leaks, wind noise, or rattles, and may even lead to paint scuffing around the hinge area.

Replace the gasket when:
 • Performing glass or hinge installation, or during body/paint restoration
 • The window shows misalignment, wind noise, or minor leakage
 • The existing seal appears cracked, brittle, or misshapen

 Replacing with a fresh gasket restores a tight seal, clean alignment, and factory-quality protection for your classic Porsche 911.

Rear 1/4 glass opening handle. 
Provides the lever action to latch, unlatch, and hold the rear quarter glass in the open or closed position, maintaining correct sealing pressure when shut and controlled ventilation when open.

Fits:
Porsche 911/912 1965 - 1977

Diagram ref no 14

• Position: Rear quarter window, left or right (handle is typically side-agnostic)
• Sold each (order two to renew both sides)

Over time, the quarter window handle can become pitted, loose, or seize due to wear, corrosion, or age. A worn handle not only detracts from appearance but can also fail to latch the glass securely, leading to rattles or water ingress.

Replace the handle when:
• The handle feels sloppy, stiff, or seized in operation.
• The window won’t stay latched or won’t hold its open position.
• Performing interior restoration, glass replacement, or seal service.

Installing a fresh handle restores proper latch function, smooth operation, and a clean, factory-correct look to your Porsche’s quarter windows.

Product Information
Product Information

Clear rear quarter window glass from OE Match for Porsche 911 Coupé applications from 1965–77, including the supplied early 912 and 930 Turbo applications. Suitable for glazing repairs and classic-car restoration.

Fits

  • Porsche 911 - 1965 to 1977 (coupe)

Check fitment for your specific vehicle (model, year, engine) before ordering.

Diagram ref no 11

What This Product Does

This panel forms the glazed section behind the door in the rear quarter window assembly. It replaces damaged glass while retaining the specified clear appearance. OE Match develops replacement components around Porsche-specific applications and original-reference checks.

Functions

  • Provides glazing for the rear quarter window opening.
  • Allows an outward view through the rear side panel.
  • Supports repair or refurbishment of the existing window assembly.

Technical Details

  • Brand: OE Match.
  • Position: rear quarter window; glass specification: clear.
  • Body application: Coupé.
  • Supplied diagram references: 90154310120 and 90154310220.
  • The 1970–73 diagram identifies 90154310120 as lhd 
  • and 90154310220 as rhd.
  • Earlier diagram entries contain additional year-specific position notes; confirm the required reference and side against the original glass.

Symptoms of Fault

  • Visible cracking or damage to the glass.
  • Unwanted or uneven tint film on the existing panel.
  • Water entering around the window seal, requiring inspection of the surrounding assembly.

Why Replacement Matters

Renewing damaged glazing helps complete a body repair or restoration with the specified clear finish. Inspect the surrounding rubber, frame and mounting components at the same time: replacing glass alone will not resolve a leak caused by deteriorated seals or poor alignment.

FAQs

  • Which body style is listed?
    The supplied application specifies Coupé bodywork.
  • What colour is the glass?
    This version is specified as clear.
  • Are frames, seals or fittings included?
    The supplied information identifies window glass only; inclusion of these additional components is not confirmed.

Product Information

OE Match rear quarter window glass with a green tint, intended for the pop-out glazing arrangement on Porsche 911 Coupe models from 1965–77. The supplied applications also identify 912 SWB and 930 Turbo variants.

Fits

  • Porsche 911 - 1965 to 1977 (Coupe)

Check fitment for your specific vehicle (model, year, engine) before ordering.

Diagram reference number: 11.

What This Product Does

This panel forms the glazed section of the opening rear quarter window. It is intended for replacement during glazing repairs or body restoration, rather than conversion to a fixed-window arrangement.

Functions

  • Replaces damaged rear quarter glazing.
  • Provides the glass panel for the pop-out window assembly.
  • Retains the specified green-tinted appearance.

Technical Details

  • Brand: OE Match.
  • Position: rear quarter window.
  • Window arrangement: pop-out/opening.
  • Glass colour: green tint.
  • Left-hand glass reference: 90154310130. lhd
  • Right-hand glass reference: 90154310230.  rhd
  • These identify separate sides

Symptoms of Fault

Cracking, deteriorated glazing or an inconsistent tint may prompt replacement. Water entering around the window also warrants inspection of the surrounding rubber seals; replacing the panel alone may not resolve a sealing fault.

Why Replacement Matters

Renewing damaged glazing supports repair or restoration while retaining the specified opening-window configuration. Check the frame, seals, hinges and securing hardware during the work, and confirm the required side before selecting the glass.

FAQs

  • Is this for fixed rear windows?
    No. The supplied specification identifies a pop-out window application.
  • Are frames and seals included?
    The supplied information does not confirm their inclusion. The diagrams identify surrounding frames, seals and hinges as separate components.
