Middle Section
This Heater Tube Inside Sill is a Genuine Porsche OE component designed to route heated air through the inner sill section of classic air-cooled Porsche 911 models from 1969 to 1989. The heater tube carries warm air produced by the engine’s heat exchangers through the sill cavity toward the cabin ventilation system.
Fits:
Porsche 911 1969 - 1989
Diagram ref no 15
Function: Installed inside the vehicle’s sill structure, the tube forms a critical part of the classic 911 heating system. It channels heated air forward into the cabin ducting, supporting effective interior heating, windscreen demisting, and overall comfort in cooler conditions.
Over time, original heater tubes can degrade due to heat cycles, age, and corrosion, resulting in reduced airflow or heat loss before reaching the cabin. In severe cases, damaged ducting may allow unwanted fumes or debris into the heating system. Replacing the tube with a Genuine Porsche part restores factory heating efficiency, preserves originality, and ensures long-term reliability of the heating system.
Replace this heater tube if you notice:
• Weak or uneven heater output
• Cracked, brittle, or collapsed ducting
• Heat loss before air reaches the cabin
• Unpleasant odours from the heating system
• During restoration or refurbishment of the sill or heating system

The OE Match Jack Receiver Socket is a replacement structural jacking-point component for classic Porsche 911 models from 1974–1989.
Fits:- Porsche 911 1974-89
Diagram Ref No 10
Mounted within the sill/body structure, the receiver provides the correctly shaped engagement point for the factory-style Porsche jack. When the jack is inserted into the socket, lifting forces are transferred from the jack through the receiver and into the surrounding reinforced body structure.
Because the receiver is positioned low on the vehicle and close to the sill, it is particularly vulnerable to moisture, road contamination, corrosion and previous incorrect lifting. On older cars, corrosion may affect not only the visible socket but also the surrounding jack receiver bracket, inner sill and adjacent structural panels.
Replacing a corroded, distorted or damaged receiver helps restore correct jack engagement and forms an important part of proper sill and chassis restoration.
What This Product Does:
The jack receiver socket provides the engagement point for the original side-entry vehicle jack.
It is designed to:
- Accept the factory-style Porsche jack.
- Keep the jack correctly positioned during lifting.
- Transfer lifting force into the reinforced sill structure.
- Maintain the original jacking-point location.
- Provide secure engagement during wheel changes and maintenance.
- Replace a rusted, bent or damaged original receiver.
- Restore correct chassis geometry around the jacking point.
- Support period-correct body restoration.
- Allow the correct jacking-point plug to be fitted where applicable.
Symptoms Of Wear Or Failure:
Possible signs of deterioration include:
- Visible rust around the receiver opening.
- Flaking or perforated metal.
- Heavy corrosion inside the socket.
- Receiver opening becoming distorted.
- Jack no longer fitting correctly.
- Jack fitting loosely in the socket.
- Jack becoming difficult to insert.
- Cracks around the receiver.
- Receiver appearing bent or twisted.
- Socket moving when pressure is applied.
- Separation from surrounding sill metal.
- Previous poor welding or patch repairs.
- Deformation caused by incorrect jacking.
- Corrosion around the adjacent sill.
- Crunching or flexing when the area is inspected.
- Paint bubbling around the jacking point.
- Rust staining emerging from seams.
Why Replacement Matters:
Replacing a damaged or corroded jack receiver helps restore:
- Correct factory-jack engagement.
- Proper jack positioning.
- Structural integrity at the jacking point.
- Correct load transfer into the sill.
- Original body geometry.
- Period-correct appearance.
- Reliable access for future servicing.
For a classic Porsche restoration, the jack receiver is both a functional structural component and an important detail of the original sill construction.
