What This Product Does
The upper Tenax component forms part of the cover's attachment system, connecting with the corresponding lower fitting. Its role is cover retention, not fabric repair or roof sealing. OE Match supplies replacement components developed around Porsche applications.
Functions
- Provides the upper component of the Tenax fastening connection.
- Retains the cover at the corresponding attachment point.
- Replaces a missing or damaged upper fitting during cover refurbishment.
Technical Details
- Brand: OE Match.
- Supplied part reference: 99959198312.
- Component identification in the supplied diagrams: Tenax upper part.
- 911 1978–83 diagram quantities: nine for the tonneau-cover assembly; the convertible-cover diagram does not state a quantity.
- 911 1984–86 diagram quantities: eight for the convertible cover and nine for the tonneau cover.
- Other diagram quantities: six for the 1987–89 911 Cabrio convertible cover, eight for its tonneau cover, ten for the 1989 Speedster and eight for the 1989–94 964 Cabrio convertible cover.
Diagram quantities describe the relevant assemblies, not the number of fasteners supplied with this product. Lower Tenax fittings, cover fabric and other diagram components are distinct parts.
Symptoms of Fault
A missing or broken cover fastener warrants inspection. Split stitching, cracked fabric or a cover that has shrunk can also affect attachment, so check the surrounding material before attributing poor fit solely to the upper fitting.
Why Replacement Matters
Renewing a damaged upper fitting addresses an incomplete fastening connection. Inspect its lower counterpart and the cover's mounting area at the same time; replacing this component will not correct torn material or a mismatched attachment.

OEMatch Tonneau Cover — Fit, Function, Confidence
OEMatch supplies tonneau covers and related items for Porsche models, selected to protect folded roofs and maintain presentation. These covers conserve interior trim and help prevent UV and moisture damage while providing a neat finish to the rear deck when the roof is down.
Available Types
- Vinyl tonneau covers in factory-correct colours
- Canvas tonneau covers with water-resistant treatment
- Trim-fitted covers matching original mounting points and fasteners
Understanding OEMatch Tonneau Cover
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original tonneau cover. OE (Original Equipment) refers to parts matching original specifications for the tonneau cover and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM tonneau cover engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch focuses on Porsche tonneau-cover items and related accessories and maintains a broad catalogue to support older and newer models. Covers are typically formed from coated textiles backed with reinforcement where needed, and are finished to match interior trim and exterior paint tones where factory references apply.
Benefits Include
- Protects folded roof assemblies from UV exposure, dirt and moisture
- Preserves upholstery and mechanisms by reducing soiling and water ingress
- Improves presentation and helps maintain resale appearance
Why Tonneau Cover Wear and Fail
- Fading or cracking from prolonged sun exposure and weathering
- Broken fasteners, stitching or worn mounting points from repeated use
- Shrinkage or deformation from incorrect storage or temperature cycling
- Damage during folding, removal or incorrect fitment
The Importance of Replacing with OEMatch Tonneau Cover
Choosing a correctly sized, well finished cover helps protect costly trim and roof mechanisms on Porsche models. A sound replacement prevents staining and moisture ingress that can lead to mould or corrosion in concealed areas and keeps the vehicle’s presentation consistent with its original appearance.
Advantages
- Available in materials and colours that match factory finishes
- Direct-fit designs minimise trimming or modification during installation
- Options for durable, weather-resistant coatings suitable for regular use
