The OE MATCH Rear Floor Pan Repair Panel is a replacement body repair panel designed for restoring the rear floor pan area of compatible Porsche 911 models.
Fits:
- Porsche 911 1966-1968 2.0L / 912 SWB (F)
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
- Porsche 911 1978-1983 3.0L / SC
- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50
- Porsche 911 1975-1977 3.0L Turbo (930)
- Porsche 911 1978-1989 3.3L Turbo (930)
Manufactured as an OE-style replacement, this panel is suitable for restoration and body repairs where the original rear floor section has suffered from corrosion, rust perforation, accident damage or deterioration caused by previous repairs.
The floor pan forms an important part of the vehicle's lower body shell. Replacing severely weakened or damaged metal helps restore a solid floor structure, provides sound joining surfaces for surrounding panels and creates a strong foundation for long-term corrosion protection.
What This Product Does:
The rear floor pan forms part of the lower body structure of the Porsche 911.
It creates a solid floor section while connecting with and supporting surrounding areas of the body shell.
Its functions include:
- Forming part of the lower body structure
- Providing a solid rear floor section
- Supporting surrounding body panels
- Maintaining the shape and integrity of the floor area
- Providing joining surfaces for adjacent panels
- Separating the interior from the underside of the vehicle
- Helping prevent water, dirt and road debris entering the cabin
- Providing a sound structural foundation for restoration work
When the original floor is badly corroded, replacing the affected section is often preferable to repeatedly patching weakened metal.
Symptoms Of Wear Or Failure:
A floor pan does not normally wear through mechanical movement. Its most common causes of deterioration are corrosion, trapped moisture, physical damage and poor previous repairs.
Signs that the rear floor pan may require repair or replacement include:
- Visible rust
- Rust bubbles beneath paint or underseal
- Perforation or holes
- Soft or weakened metal
- Heavy surface pitting
- Flaking metal
- Cracks or splits
- Corrosion around seams
- Failed spot-welded areas
- Water entering the cabin
- Damp carpets or insulation
- Distorted floor sections
- Damage caused by incorrect lifting
- Failed previous patch repairs
- Separation between overlapping panels
- Excessive seam sealer hiding deterioration
Corrosion should always be assessed beyond the immediately visible area.
Why Replacement Matters:
A heavily corroded rear floor pan is more than a cosmetic issue.
The floor forms part of the body shell, and extensive deterioration can weaken the panel itself and the connections between adjoining sections.
Replacing damaged metal helps:
- Restore the integrity of the rear floor
- Remove perforated and weakened steel
- Provide sound metal for welding
- Restore correct panel geometry
- Reinstate secure joints with adjoining panels
- Reduce the risk of water and debris entering the interior
- Prevent corrosion being hidden underneath additional patches
- Provide a solid foundation for underbody protection
- Improve the quality and longevity of a restoration
For a classic Porsche restoration, replacing extensively deteriorated steel can provide a considerably better long-term repair than simply covering it.

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

This heating tube inside sill is a high-quality replacement air-duct tube designed to channel warm air from the exhaust-heated heating system through the sill area of classic Porsche 911 models built from 1969 through 1989 and 356 B/C models. It matches the original part’s fit and performance to maintain proper heating airflow in your vehicle’s cabin.
Fits:
Porsche 356 B/C 1.6 01/1959 - 12/1965
Porsche 911 2.0-3.3 08/1968 - 07/1989
Porsche 912 1.6 01/1965 - 02/1970
Porsche 914 1.7-2.0 01/1969 - 07/1974
Diagram ref no 15
The heating tube directs hot air generated by the engine’s exhaust-heated heat exchangers into the cabin area via the sill ducting. This ensures your classic Porsche’s heater system distributes warmth effectively, improving defogging, defrosting, and passenger comfort in cooler weather.
Function: Installed along the inner sill section, this tube captures heat from the heater system and delivers it through the duct network into the footwell or cabin air distribution points. A properly functioning heater tube helps maintain consistent cabin temperature and prevents heat loss due to damage or age-related degradation of the original ducting.
Over decades of use, original heater tubes can become cracked, brittle, or collapsed, leading to poor airflow, heat loss, or even exhaust gas intrusion into the cabin air system. Replacing the deteriorated tube with an OE Match unit restores effective hot-air distribution, improves cabin comfort and heater efficiency, and keeps the vintage heating system functioning as intended.
Replace this heating tube when you notice:
• Weak or inconsistent warm air delivery from the heater
• Deteriorated, cracked, or collapsed heater tubing
• Excessive heat loss before reaching the cabin
• Unusual smells from heater ducts (possible leaks)
• During full heater system or sill restoration work
