Front Targa Roll Bar Seal 

Restore the weatherproof integrity and original fit of your classic Porsche with this OE Match Front Targa Roll Bar Seal, designed specifically for Porsche 911 Targa models from 1965 to 1969. Manufactured to OE specifications, this high-quality rubber seal fits along the front edge of the Targa roll bar, creating a secure seal between the removable roof panel and the stainless steel Targa bar.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)

Diagram Ref: 41

As one of the key weather seals on early Targa models, this component plays an essential role in preventing water ingress, reducing wind noise and ensuring the roof panel fits securely against the body. Over decades of exposure to sunlight, moisture and changing temperatures, the original seal naturally hardens and deteriorates, reducing both comfort and weather protection.

This OE Match replacement restores the correct fit, sealing performance and factory appearance expected from an early Porsche 911 Targa.

What Does the Front Targa Roll Bar Seal Do?

The front roll bar seal forms a weather-tight seal between the removable Targa roof panel and the front face of the Targa roll bar.

Its primary functions include:

• Preventing water entering the cabin
• Reducing wind noise
• Cushioning the roof panel
• Supporting correct roof alignment
• Eliminating rattles and vibration
• Protecting the interior from moisture
• Maintaining the factory roof fit

A correctly fitted seal helps preserve the unique open-top driving experience while maintaining comfort in all weather conditions.

Why Do Targa Roll Bar Seals Fail?

Rubber weather seals are continually exposed to the elements and naturally deteriorate with age.

Common causes of failure include:

• UV exposure
• Moisture damage
• Rubber hardening
• Shrinkage
• Cracking
• Compression set
• General age-related deterioration

Even well-maintained cars will eventually require replacement seals to restore proper sealing performance.

Symptoms of a Worn Front Targa Roll Bar Seal

Common signs include:

• Water leaks around the roof
• Increased wind noise
• Whistling at speed
• Roof rattles
• Flattened or cracked rubber
• Gaps between the roof panel and roll bar
• Damp interior trim
• Visible deterioration of the seal

Replacing worn seals dramatically improves cabin refinement and weather protection.

When Should the Seal Be Replaced?

Replacement is recommended when:

• Water leaks develop
• Wind noise increases
• The rubber becomes hard or cracked
• Carrying out a Targa roof restoration
• Repainting the vehicle
• Refurbishing the roof panel
• Completing a concours restoration
• Undertaking preventative maintenance

Many Porsche restorers replace all Targa seals together to ensure consistent sealing and long-term reliability.

Why Replace with an OE Match Seal?

A correctly manufactured OE Match seal offers:

• Factory-style fitment
• Excellent weather protection
• Reduced wind noise
• Improved roof stability
• Long-lasting rubber compound
• Correct appearance
• Easy installation
• Reliable sealing performance

Replacing ageing weather seals is one of the most effective ways to restore the comfort and usability of a classic Porsche Targa

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

Diagram Ref: 42

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
