Targa Top Seals

Rear targa roof seal

This replacement gasket fits at the back of the removable roof where it meets the roll bar, helping maintain the seal and cushion the contact between these components.

Fits:

• Porsche 914 1970-1973 (up to VIN 47329 26221)

Diagram ref no 14

What This Product Does

The rear seal closes the joint between the targa roof panel and roll bar. It helps restrict water, draughts and exterior noise from entering the cabin while supporting a secure roof fit. A sound seal can also reduce squeaks caused by contact and movement between the roof and surrounding structure.

Functions

• Seals the rear edge of the removable targa roof
• Helps limit water and air entering through the roof joint
• Cushions contact between the roof panel and roll bar
• Helps reduce roof-related squeaks and rattles

Technical Details

• Position: rear of the targa roof
• Component description: roof-to-roll-bar gasket
• Available as self-adhering foam or high-quality rubber with a bonded fuzzy edge
• Applicable to early Porsche 914 production up to VIN 47329 26221
• Exploded diagram reference: 14

Symptoms of Fault

• Water entering around the rear corners of the roof
• Wind whistle or increased cabin noise at speed
• Squeaks or creaks from the targa panel over uneven surfaces
• Flattened, split, hardened or missing sealing material
• Visible gaps between the roof and roll bar
• Damp trim, condensation or musty odours inside the cabin

Why Replacement Matters

Age, sunlight, repeated roof removal and long-term compression can cause the original seal to shrink, harden or lose its shape. Replacing a deteriorated gasket helps restore the roof joint, reduce unwanted noise and protect the cabin and trim from moisture. Roof latches, panel alignment and adjacent seals should also be inspected, as these parts work together to provide an effective seal.

FAQs

• Does this seal fit every Porsche 914?
  No. This application is specified for 1970–73 cars up to VIN 47329 26221, so the chassis number should be checked before selection.
• Why might the roof still leak after fitting a new seal?
  Roof-panel alignment, latch adjustment, side seals and drainage paths can also affect water sealing. Inspect these areas before making final adjustments.
• What should be checked during installation?
  Clean the mounting surface thoroughly and avoid stretching the seal. Confirm that the roof panel sits evenly and allow new sealing material time to settle before final latch or alignment adjustments.

Targa top-to-window seal set

Supplied as a matched left and right pair, these seals close the joint between the removable roof panel and the raised side windows.

Fits

• Porsche 914 1970–76

Diagram ref no 20

What This Product Does

The seals form a weather barrier where the door glass meets each side of the Targa roof. Replacing hardened, split or compressed seals can help address water entry, wind whistle and movement-related squeaks while protecting the cabin and interior trim from moisture.

Functions

• Seals the left and right roof-to-side-glass interfaces
• Helps prevent rainwater, draughts and dust entering the cabin
• Reduces wind noise caused by gaps around the raised windows
• Supports correct contact between the side glass and roof panel
• Replaces both sides during the same repair

Technical Details

• Set contents: one left seal and one right seal
• Left OE reference: 91453118510
• Right OE reference: 91453118610
• Uses the revised 1974–76 gasket profile with an additional sealing lip
• Original application: Porsche 914 1.8 and 2.0 models from 1974
• The later profile may also be fitted to earlier 1970–73 cars

Symptoms of Fault

• Water entering near the upper corners of the side windows
• Wind whistle or increased cabin noise at speed
• Flattened, torn, cracked or hardened sealing surfaces
• Damp trim, carpets or musty cabin odours
• Squeaks or creaks from the removable roof assembly
• Visible gaps between the roof seal and raised window glass

Why Replacement Matters

Age, sunlight, temperature changes and repeated roof removal can reduce the flexibility of the original seals. Renewing both sides together helps provide consistent contact around the roof panel, limits moisture reaching the interior and supports a more uniform roof and window fit. Window alignment, roof latches and adjoining seals should also be checked during installation.

FAQs

• Why can a new seal make the roof or window harder to close? Fresh rubber may require time to settle. Confirm the roof and window alignment rather than forcing the latch or glass.
• What should be checked if water still enters after fitting? Inspect the roof latches, window adjustment, drainage paths and adjacent front and rear Targa seals.
• How should the seals be installed? Clean the mounting channels and fit each seal without stretching it. Allow the pair to compress before making final alignment adjustments.

Vertical Targa Roof Seal Set

This replacement set renews the upright seals located between the rear edges of the door windows and the roll bar.

Fits

• Porsche 914 (1970–1976)

Diagram ref no 36

What This Product Does

Each vertical seal fits into the aluminium retaining channel on the roll bar and closes the joint behind the door glass. The formed sealing lip helps restrict water, draughts and wind noise from entering the cabin when the windows and removable roof are correctly aligned.

Functions

• Seals the rear vertical edge of each door window
• Fits within the roll-bar aluminium channels
• Helps limit water ingress around the side glass
• Reduces air gaps and wind whistle
• Supports correct sealing of the Targa roof system

Technical Details

• Complete left- and right-hand vertical seal set
• Left-hand OE reference: 91453114310
• Right-hand OE reference: 91453114410
• Location: rear edge of the door glass on the roll bar
• One complete set is required per vehicle
• Exploded-parts diagram reference: 36

Symptoms of Fault

• Water entering near the rear corners of the side windows
• Wind whistle or increased cabin noise at speed
• Cracked, hardened, flattened or torn rubber
• Visible gaps between the glass and roll-bar seal
• Damp trim, carpets or musty cabin odours
• Squeaks or rattles around the Targa roof and door glass

Why Replacement Matters

Age, sunlight, temperature changes and repeated compression can cause the original rubber to shrink or lose flexibility. Renewing both vertical seals can restore a continuous contact surface around the door glass, helping to protect the cabin and surrounding trim from moisture. Window position, roof alignment, latches and drainage paths should also be inspected, as these work together with the seals to provide effective weather protection.

FAQs

• Where are these seals installed?
  They slide into the upright aluminium channels on the roll bar, directly behind the door windows.
• Does the set cover both sides?
  Yes. It contains the corresponding left- and right-hand vertical seals.
• Why might a Porsche 914 still leak after fitting new seals?
  Check the window adjustment, roof latches, adjoining seals and drainage paths. Correct alignment is necessary for consistent contact.
• Is fitting preparation important?
  Yes. Clean the retaining channels and surrounding surfaces thoroughly, and avoid stretching the rubber during installation.
