Fastening Angle Seat Belt.

The OE Match Seat Belt Fastening Angle is a replacement mounting bracket for the seat-belt installation on classic Porsche 911 models from 1969–1973.
Price Is For Each.

Fits:
  • Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

Diagram Ref No 5

Available in specific left- and right-hand versions, the fastening angle forms part of the seat-belt mounting arrangement and provides a secure mounting position for the associated restraint hardware.

These OE Match components are particularly suitable for restoration or replacement of original brackets that have become corroded, bent, damaged or are missing.

What This Product Does:
The fastening angle provides a rigid mounting point within the seat-belt installation.

Seat belts rely on correctly positioned and structurally secure anchorages to restrain the occupant during sudden braking or a collision. The fastening angle helps position and support the relevant seat-belt attachment hardware in the intended factory location.

Its functions include:

  • Providing a secure mounting point for seat-belt hardware
  • Maintaining correct positioning of the belt attachment
  • Supporting the original seat-belt installation geometry
  • Providing a rigid connection between the restraint hardware and mounting structure
  • Helping keep the seat belt correctly aligned
  • Restoring the factory-style mounting arrangement during vehicle restoration

Because this component forms part of the occupant restraint system, its structural condition and correct installation are particularly important.

Symptoms Of Wear Or Failure:
The fastening angle is a metal component, but age, moisture, corrosion and previous repairs can compromise its condition.

Common signs that replacement may be required include:

  • Visible rust or corrosion
  • Heavy surface pitting
  • Cracks around mounting holes
  • Bent or distorted bracket
  • Enlarged or damaged mounting holes
  • Loose seat-belt attachment
  • Bracket moving when the belt is pulled
  • Missing fastening angle
  • Damage caused by previous seat or interior modifications
  • Incorrectly positioned seat-belt mounting hardware
  • Evidence of previous accident damage
  • Severe corrosion discovered during restoration
  • Mounting hardware that can no longer be tightened securely

Any seat-belt anchorage showing structural damage or significant corrosion should be inspected carefully before the vehicle is used.

Why Replacement Matters:

  • The seat belt is a primary safety system, and its mounting components must remain strong and securely attached.
  • A corroded, cracked or distorted fastening angle may not support the seat-belt attachment as intended. Excessive movement can also affect belt positioning and place abnormal loads on related mounting hardware.
  • Because seat belts can experience very high forces during a collision, seemingly minor deterioration in an anchorage component can be significant.
  • Replacing a damaged fastening angle helps restore the intended mounting arrangement and ensures the associated seat-belt hardware can be secured correctly.
  • For restoration work, renewing heavily corroded or previously modified brackets is also preferable to reusing components whose structural integrity may be uncertain.

Product Information
Foam for headrest, "Peanut-shape", adjustable
This headrest foam is a replacement inner foam pad for the adjustable “peanut-shape” headrest used on classic Porsche 911 models from 1968 to 1973. It is designed to help restore the correct headrest shape, support, and appearance during seat trimming or interior restoration.

Fits:
Porsche 911 2.0L-2.7L 09/1968 - 07/1973

The headrest foam sits inside the headrest cover and provides the padding, structure, and contour of the headrest. It helps give the headrest its correct period-style peanut shape while improving comfort and restoring the original look of the seat assembly.

Functions
•  Replaces the inner foam for the adjustable peanut-shape headrest
•  Helps restore the correct classic Porsche headrest profile
•  Provides padding and support inside the headrest cover
•  Improves comfort and headrest appearance
•  Replaces collapsed, brittle, crumbling, or misshapen original foam
•  Suitable for seat trimming and interior restoration work
•  RetroLine replacement for classic Porsche seat refurbishment.

Why Replace This Part?
Original headrest foam can deteriorate with age, heat, compression, and long-term use. Over time, the foam may collapse, crumble, harden, lose shape, or no longer fill the headrest cover correctly. Replacing the foam helps restore the correct shape, comfort, and presentation of the original adjustable headrest.

When to Replace This Part
•  The headrest foam has collapsed or lost its shape
•  The headrest feels hard, flat, uneven, or unsupported
•  The original foam is crumbling, brittle, or damaged
•  The headrest cover is being replaced or retrimmed
•  The seat interior is being restored
•  The headrest no longer has the correct peanut-shape profile
•  The vehicle is undergoing Porsche 911 interior restoration.

Where it fits on the car
This foam fits inside the adjustable peanut-shape headrest fitted to Porsche 911 seats. It is used as the internal padding beneath the headrest upholstery cover.
