Rear End Cap For Wide Deco Sill / Rocker.

The OE Match Rear End Cap for Wide Deco Sill / Rocker is a premium-quality replacement trim component designed to finish and protect the rear section of the wide sill (rocker) moulding on compatible classic Porsche models. Manufactured to OE specifications for fit, profile and durability, these end caps provide a neat factory-style finish while helping to shield the ends of the rocker trim from dirt, moisture and impact damage.

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 No 29

Manufactured from high-quality automotive-grade material with excellent resistance to UV exposure, weathering and road debris, each end cap is precision-moulded to replicate the original Porsche design. Designed for direct OE-style installation, they fit seamlessly with the wide decorative sill moulding, making them ideal for restoration projects or replacing damaged or missing originals.  

What This Product Does:
  • Finishes the rear end of the wide rocker/sill moulding.
  • Protects the sill trim from impact and environmental damage.
  • Helps prevent dirt and moisture from entering the trim assembly.
  • Completes the factory appearance of the lower bodywork.
  • Provides secure OE-style fitment.
  • Helps maintain correct alignment of the rocker moulding.
  • Replaces worn, damaged or missing end caps.
  • Forms an integral part of the exterior body trim system.

Symptoms Of Wear Or Failure:
  • Missing or broken end cap.
  • Cracks or impact damage.
  • Loose or poorly fitting trim.
  • Faded, scratched or weathered finish.
  • Gaps at the end of the rocker moulding.
  • Dirt and moisture entering behind the sill trim.
  • Increased vibration or rattling from the moulding.
  • Corrosion developing around the sill trim area.
  • Reduced originality of the vehicle's exterior.
  • Poor cosmetic appearance following restoration.

Why Replacement Matters:
  • The rear rocker end caps are continuously exposed to road spray, stone impacts, UV radiation and changing weather conditions. Over time, they can become cracked, worn or detached, leaving the ends of the sill moulding exposed to moisture and debris.
  • A damaged or missing end cap can allow dirt and water to accumulate behind the rocker trim, increasing the risk of corrosion while detracting from the vehicle's factory appearance. Loose trim may also vibrate during driving, potentially causing damage to surrounding bodywork or moulding components.
  • Replacing worn or damaged rear end caps restores the original finish of the rocker moulding while helping to protect the sill assembly from environmental damage. The OE Match replacements provide factory-style fitment, durable construction and long-lasting performance, making them an excellent choice for Porsche restoration, repair and preventative maintenance.

Side Sill Moulding + Rubber Seal.
The OE Match Side Sill Moulding with Rubber Seal is a premium-quality replacement exterior trim component designed to restore the original appearance and protection of the side sill on compatible classic Porsche models. Manufactured to OE specifications for fit, profile and durability, this assembly combines the decorative sill moulding with an integrated rubber seal to provide a factory-correct finish while helping protect the bodywork from dirt, moisture and road debris.  

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 No 33

Manufactured from high-quality corrosion-resistant materials with a durable finish, the moulding is paired with a premium automotive-grade EPDM rubber seal that offers excellent resistance to UV exposure, ozone, moisture and temperature extremes. Precision-engineered for direct OE-style installation, this complete assembly ensures accurate fitment and is ideal for restoration projects or replacing worn, damaged or missing original trim.

What This Product Does:  
  • Restores the original appearance of the side sill.
  • Protects the sill area from road debris and moisture.
  • Provides a weather-resistant seal between the moulding and body.
  • Helps prevent dirt and water from collecting behind the trim.
  • Reduces vibration and movement of the moulding.
  • Enhances the appearance of the vehicle's lower bodywork.
  • Provides factory-style fitment and alignment.
  • Forms an integral part of the exterior body trim system.

Symptoms Of Wear Or Failure:
  • Loose or detached sill moulding.
  • Cracked, bent or damaged trim.
  • Perished, split or hardened rubber seal.
  • Moisture or dirt trapped behind the moulding.
  • Corrosion developing along the sill.
  • Rattling noises from loose trim.
  • Faded, scratched or deteriorated finish.
  • Visible gaps between the moulding and body.
  • Poor alignment or insecure fitment.
  • Reduced originality and cosmetic appearance.

Why Replacement Matters:

  • The side sill moulding and rubber seal are continually exposed to road spray, stone impacts, moisture, road salt and UV radiation. Over time, the trim can become damaged while the rubber seal may harden, crack or shrink, reducing its ability to protect the bodywork and maintain a secure fit.
  • A deteriorated moulding assembly can allow moisture and debris to accumulate behind the trim, increasing the risk of corrosion and damaging the underlying sill panel. Loose trim may also vibrate during driving and detract from the authentic appearance of a classic Porsche.
  • Replacing the side sill moulding and rubber seal restores the factory appearance, protects the bodywork from environmental damage and ensures secure OE-style fitment. The OE Match replacement provides premium-quality materials, precise construction and long-lasting durability, making it the ideal choice for restoration, repair and long-term preservation of your Porsche.

Side Sill Moulding + Rubber Seal.
It is a wide type decorative sill panel with a rubber insert that was fitted to the long wheelbase Porsche 911 from 1969 through 1973. The moulding is sized to approximately 59.5″ long and fits either left or right side of the vehicle. This exterior body-trim part sits along the lower rocker (side sill) area below the doors

Fits:
Porsche 911 1969-73 (LWB)
Long Wheel Base Cars

Diagram Ref No. 25

The side sill moulding serves both aesthetic and protective roles on the vehicle’s lower bodywork:
Protects the rocker panel from minor impacts, road debris, and scrapes
 Accentuates the classic body line, contributing to the vehicle’s period-correct look
 The rubber seal helps bridge the gap between the trim and body, reducing moisture ingress behind the moulding and offering a more finished appearance
 Helps maintain authentic exterior style on restored or well-maintained classic vehicles.

Over decades on the road, original sill mouldings and seals can:
 Fade, crack, or warp
 Lose adhesion or proper fit
 Expose underlying rocker panels to corrosion or damage.

Replacing worn or missing sill trim restores the correct visual line and offers renewed protection for the lower bodywork - especially important on restored vehicles or those being prepared for show-quality presentation.

Replace this side sill moulding if:
  The original trim is missing, cracked, split, or faded
   Rubber insert has hardened or detached
   Re-assembling after bodywork or repaint
   During a body restoration or concours detailing project
