This Porsche Genuine OE Expansion Rivet is a factory plastic push-type fastening clip designed for securing the door sill step plate / threshold trim. Commonly referred to as a plastic rivet, expanding rivet, or trim clip, this component is widely used in classic Porsche models for fastening interior and exterior trim panels.
Sold individually, Typically multiple required per vehicle
Fits:
Porsche 911 1965 - 1973
Porsche 914 1970 - 1976
Diagram ref no 29
It replaces earlier reference 99959152640 and is supplied individually.
This is a multi-use trim fastening clip, also used in other interior applications depending on model and configuration.
This expansion rivet is inserted into pre-drilled holes and expands when pushed into place, locking the door sill plate or trim strip securely to the bodywork.
It provides a firm hold while allowing easy installation and removal, making it ideal for trim components that may require periodic servicing or replacement.
Functions & Technical Role
• Trim fastening: Secures door sill step plates and threshold trims
• Expansion locking design: Expands inside mounting holes for secure retention
• Vibration resistance: Prevents movement, rattling, or loosening of trim
• Non-corrosive material: Plastic construction resists rust and environmental damage
• OEM precision: Designed to Porsche specifications for correct fit and grip
Fitment / Position on car
• Fitting position: Interior / body trim
• Location: Door sill step plates (threshold trims) / Rocker panel trim strips / Interior trim panels (various applications)
Trim clips are often overlooked but are critical for maintaining proper fit and finish. Over time, they can:
• Become brittle or break
• Lose tension and fail to hold trim securely
• Be lost during removal or restoration work
A worn or missing rivet can lead to:
• Loose or rattling sill trims
• Poor alignment of interior panels
• Reduced overall finish quality
Replacing with genuine Porsche OE rivets ensures secure trim mounting and preserves the original appearance of the vehicle.

The strip covers the sill surface alongside the doorway, completing the entry area's trim. Its scuff-plate function helps shield the covered paint from footwear contact during access to the cabin.
Functions
- Covers the exposed sill beneath the doorway.
- Completes the transition between surrounding trim surfaces.
- Provides a sacrificial contact surface against everyday scuffing.
- Replaces a missing, cracked or visibly worn sill strip.

- Left references: 981504467801E0 / 981504467811E0

Symptoms of Fault
- Heavy scratches, fading or worn contact surfaces.
- Cracking or distortion beside mounting locations.
- Loose trim accompanied by rattling.
- Uneven alignment with neighbouring panels.
- Damaged or missing attachment hardware.
Why Replacement Matters
Renewing damaged sill trim restores the finish around the doorway and replaces the worn protective surface. Check the panel beneath and all mounting points first, as replacement trim cannot remedy distorted bodywork or failed supporting fixings.
