This original-style rubber seal helps prevent water ingress, wind noise and draughts, making it ideal for replacing worn or deteriorated seals during roof maintenance or classic Porsche restoration.

What Does the Front Windscreen Frame Seal Do?

The seal creates a flexible barrier between the windscreen frame and the roof assembly. It helps prevent rainwater and wind entering the passenger compartment while maintaining correct contact between the roof and bodywork.

Why Does It Fail?

Over time, the rubber can harden, shrink, crack or become permanently compressed. Exposure to sunlight, changing temperatures and repeated roof operation can accelerate deterioration.

A worn seal may cause water leaks, excessive wind noise or visible gaps around the front roof edge.

When Should It Be Replaced?

Replacement is recommended when the seal becomes cracked, flattened, brittle or distorted, or when water and draughts enter around the top of the windscreen.

Inspect the seal whenever carrying out Targa roof refurbishment, hood repairs or windscreen frame maintenance.

Confirm the correct seal against the vehicle's roof design and original part number before ordering.

Checks During Replacement

Inspect the windscreen frame, roof alignment, retaining channels and adjacent weatherstrips. Incorrect roof adjustment or damaged surrounding seals may cause leaks even after fitting a new front seal.

Porsche 911 Targa & Cabriolet Windscreen Frame Seals

The front windscreen frame seal is an important part of the Porsche 911 roof weatherproofing system. It provides a flexible sealing surface between the windscreen frame and the Targa roof or Cabriolet hood.

As original rubber deteriorates, water leaks and wind noise can develop. OE Match seal 91156509047 provides an original-style replacement for selected Porsche 911 Targa and Cabriolet applications from 1967–1985.

Design911 supplies Porsche Targa roof seals, Cabriolet hood weatherstrips, windscreen frame seals and associated restoration components for classic Porsche 911 models.

Designed as an original-style replacement fixing, this plastic rivet helps retain the Targa roof weather seal in its correct position, supporting a secure fit and maintaining the original roof sealing arrangement.

Ideal for replacing broken, missing or damaged original rivets during Targa roof seal replacement, roof refurbishment or classic Porsche restoration.

What Does the Targa Seal Plastic Rivet Do?

The plastic rivet is used to secure the Targa roof seal to its designated mounting position.

The Targa roof relies on correctly fitted weather seals to help prevent water, wind and road noise from entering the passenger compartment.

This retaining rivet helps keep the seal correctly located, preventing unwanted movement or displacement during roof installation, removal and normal vehicle use.

Although small, it is an important fixing component when maintaining or restoring the Targa roof sealing system.

Why Do Targa Seal Plastic Rivets Fail?

Plastic retaining rivets can deteriorate over time, particularly on classic Porsche vehicles where the original fittings may be several decades old.

Common causes of failure include:

• Plastic becoming brittle through age
• Exposure to sunlight and temperature changes
• Damage during Targa roof seal removal
• Repeated roof maintenance and refurbishment
• Incorrect removal or installation
• Cracking or breaking of the retaining head
• General wear and deterioration

Once damaged, the rivet may no longer hold the seal securely in its intended position.

When Should It Be Replaced?

Replacement is recommended whenever a plastic rivet is broken, missing, loose or no longer provides secure retention.

Typical signs include:

• Missing Targa seal fixing points
• Broken or cracked rivet heads
• Loose or displaced sections of weather seal
• Rivets damaged during seal removal
• Brittle or deteriorated original plastic
• Insecure fitting following roof refurbishment

It is advisable to inspect the retaining rivets whenever replacing or adjusting the Targa roof seals.

Checks During Replacement

When replacing the Targa seal plastic rivet, inspect the surrounding roof sealing components.

Check that the weather seal is correctly positioned and free from splits, distortion or excessive compression.

Inspect the retaining holes and mounting surfaces for damage, ensuring the replacement rivet can be fitted securely without excessive force.

If the roof seal has become hardened, flattened or damaged, replacing the rivet alone may not resolve wind noise or water leaks.

Ensure all retaining points are correctly secured before refitting or adjusting the Targa roof.

Porsche 911 & 964 Targa Roof Seals, Plastic Rivets & Weatherstrip Fixings

Maintaining the Targa roof sealing system is essential for protecting the interior of classic Porsche 911 and 964 Targa models against water ingress, wind noise and unwanted draughts.

The Targa roof uses a combination of rubber weather seals, retaining components and carefully positioned mounting points to achieve an effective seal between the removable roof panel and the vehicle body.

Over time, original plastic retaining rivets can become brittle, cracked or damaged, particularly when removing aged roof seals during restoration work. Replacing damaged or missing retaining rivets helps ensure that the Targa weather seals remain correctly positioned and securely attached.

This small but important component is particularly useful during Targa roof refurbishment, weatherstrip replacement, leak repairs and complete classic Porsche restoration projects.

Rear of roll bar seal.
The rear window to roll bar seal acts as a critical weather barrier, preventing water, wind, and road debris from entering the cabin around the rear glass area. It also helps reduce wind noise and ensures that the Targa top assembly fits cleanly and snugly, maintaining the iconic look and function of the Porsche Targa design.

Fits:
Porsche 911 1965 - 1989
Porsche 964 1989 - 1994

• Application: Fits rear glass to roll bar sealing interface on classic Targa cars. One seal per car. Designed to match original factory dimensions and mounting locations for a direct replacement fit.
• Function: Weatherproofing between rear glass & roll bar
• Benefits: Prevents leaks, reduces noise, restores original fit & finish

Installed along the top edge of the rear glass where it meets the Targa roll bar, this gasket provides a consistent sealing surface that keeps out moisture and airflow while preserving the structural integrity and classic silhouette of your Porsche. It supports long-term durability for road driving and contributes to the car’s overall comfort and weather resistance. 

Over time, the original rear window seal can harden, crack, or compress due to aging, UV radiation, and temperature fluctuations. When the seal isn't functioning properly, moisture can leak into or into the cabin, causing water spots, fogging, and potential corrosion. Replacing this seal with a new, high-quality seal restores proper weather protection, keeps the interior dry and quiet, and helps preserve the value and authenticity of your classic Porsche.

Replace the rear Targa roll bar seal if you notice:
• Cracks, splits, or visible hardening of the seal
• Water leaks or dampness around the rear window
• Increased wind noise at higher speeds
• Loose or compressed seal no longer providing firm contact
• During restoration or Targa top refurbishment

Designed to replicate the original sealing arrangement, they help create a weather-resistant barrier between the Targa roof and the upper edges of the side windows, reducing water ingress, wind noise and unwanted draughts.

Ideal for replacing hardened, cracked, flattened or damaged original seals during routine Targa roof maintenance, roof refurbishment or a complete classic Porsche restoration.

What Do Targa Top Lateral Seals Do?

The lateral seals run along the sides of the removable Targa roof panel, creating a protective seal against the upper edges of the door glass when the windows are closed.

Their primary functions include:

Helping prevent rainwater entering around the top of the door glass Reducing wind noise at higher road speeds Preventing unwanted draughts entering the passenger compartment Providing a flexible contact surface between the roof and window glass Helping maintain the correct Targa roof sealing arrangement Supporting comfortable, weather-resistant driving

Correctly fitted lateral seals are particularly important on Targa models because the removable roof and frameless door glass must align correctly to achieve an effective seal.

Why Do Targa Lateral Seals Fail?

Original Targa roof seals are exposed to sunlight, temperature changes, moisture and repeated compression from the door glass.

Over time, the rubber can deteriorate and lose its ability to form an effective seal.

Common causes of failure include:

Rubber hardening through age Cracking or splitting Flattening from prolonged compression Shrinkage or distortion Exposure to UV light and changing temperatures Damage during roof removal or installation Incorrect door glass adjustment Poor roof alignment or worn roof components

As the rubber deteriorates, gaps may develop between the window glass and the Targa roof, allowing water and wind noise into the vehicle.

When Should Targa Lateral Seals Be Replaced?

Replacement is recommended whenever the original seals show signs of damage or no longer provide an effective seal.

Typical indications include:

Water entering above the side windows Excessive wind noise around the Targa roof Draughts entering at the top of the door glass Hardened, cracked or split rubber Flattened or permanently compressed sealing surfaces Visible gaps between the roof seal and window glass Loose or distorted sections of weatherstrip Deterioration discovered during Targa roof refurbishment

Replacing worn lateral seals can help restore the original weather protection of the vehicle, provided the roof and door glass are correctly adjusted.

Fitment should be confirmed against the original roof seal profile and vehicle specification, particularly where a replacement or refurbished Targa roof has previously been installed.

Checks During Replacement

When replacing the Targa top lateral seals, inspect the complete roof sealing system to ensure the new rubber provides an effective fit.

Check the front and rear Targa roof seals for deterioration, and inspect the roof frame, retaining components and mounting channels for damage.

The door glass should also be checked for correct height, angle and alignment. Incorrect window adjustment can prevent even a new lateral seal from making proper contact.

Ensure the roof panel sits correctly against the windscreen frame and rear Targa bar before assessing the sealing contact.

Where necessary, adjust the roof and door glass according to the Porsche workshop procedure.

Porsche 911 Targa Roof Lateral Seals & Door Glass Weatherstrips

Maintaining the Targa roof sealing system is essential for protecting the interior of classic Porsche 911 Targa models against water ingress, wind noise and unwanted draughts.

Unlike a fixed-roof Coupé, the Porsche 911 Targa uses a removable roof panel with flexible rubber seals along its front, rear and lateral edges. The side seals are particularly important because they must provide consistent contact with the frameless door glass.

Over time, the original lateral weatherstrips can become hardened, flattened, cracked or distorted, reducing their effectiveness and allowing moisture or wind noise to enter the passenger compartment.

Replacing worn lateral seals helps restore the original roof sealing arrangement, improves contact with the door glass and contributes to a more comfortable driving experience.

These seals are suitable for routine maintenance, Targa roof refurbishment, water leak repairs and complete classic Porsche restoration projects.

• Water ingress into interior trim and carpets
• Excessive wind noise or whistling
• Poor window alignment and rattles
• Reduced roof stability and overall cabin comfort.
Replacing the seal restores a tight, clean Targa-top closure and protects the interior from the elements.
