1984 Porsche Targa Rear Seat Parts: A Comprehensive Guide

The 1984 Porsche 911 Targa represents a transitional era in the marque's history, blending classic lines with the improved performance and comfort of the G-body generation. While the rear seats of these cars are seldom used for actual passengers, they are a critical element of the interior for restorers and enthusiasts seeking a period-correct look. Whether you are rebuilding a basket-case project or simply refreshing a daily driver, knowing your options for rear seat parts—from cushions and backrests to hardware and trim—saves time, money, and frustration. This guide covers everything owners need to understand about sourcing, choosing, and installing 1984 Porsche Targa rear seat parts.

Understanding the 1984 Porsche Targa Rear Seat Configuration

The 1984 911 Targa came standard with a rear seat package that offered two small individual seats or a continuous bench, depending on the original option code. Most US-market cars featured the “jump seats” that fold flat to create a luggage area. These seats are notoriously narrow and lack legroom, but they contribute to the car’s identity as a sports car that can (theoretically) carry two small children or extra cargo.

Original Equipment vs Aftermarket Parts

Porsche original equipment (OE) parts are the gold standard for authenticity. For 1984 Targa rear seats, OE components include the foam cushions, upholstery covers, hinge mechanisms, and seat belt brackets. Porsche Classic still reproduces some interior items, but many specific rear seat parts are discontinued. Aftermarket manufacturers step in to fill the void, offering reproduction seat foam, vinyl or leather covers, and metal brackets. The key difference lies in material quality and fitment: OE parts guarantee correct grain and color matching, while aftermarket parts vary from excellent down to poor. When budget allows, OE or high-quality aftermarket is recommended.

Common Rear Seat Components

• Seat cushion and backrest foam – Often collapsed or crumbling in cars over three decades old.
• Upholstery covers – Available in leather, leatherette, or basketweave cloth, matching the front seats.
• Hinge and latch hardware – Allows the seat to fold; often seized or broken.
• Seat belt assemblies – Lap belts only for rear seats; webbing and retractors degrade.
• Trim panels and carpet – Covers the sides and floor around the seats.
• Mounting brackets – Prone to rust or stripping.

Sourcing 1984 Porsche Targa Rear Seat Parts

Finding the right parts requires a strategic approach. Because the 1984 Targa shares many interior components with other 911 models from 1974 to 1989, interchangeability is broad, but not everything fits perfectly. Focus on parts specifically for coupe or targa body styles (the targa has a different rear shelf due to the roll bar).

Used and NOS Parts

Original used parts sourced from salvage yards or private sellers can be a cost-effective route, especially for metal hardware and brackets. Look for cars that have been stored indoors to avoid faded upholstery. New old stock (NOS) parts – still in original Porsche packaging – turn up occasionally on specialty forums or from vintage Porsche parts dealers. They offer the best fitment but come at a premium. When buying used, inspect the foam for cracks, check the integrity of seat hinges, and examine the upholstery for tears or sun damage.

Reproduction Parts

Several aftermarket companies specialize in Porsche 911 interior restoration. They reproduce seat foam using modern materials that are more durable than the originals, and they offer upholstery kits in factory-correct patterns. For 1984 models, the door handle, seat release knobs, and carpet sets are also commonly reproduced. Be cautious with “universal” parts; some suppliers cut corners on foam density or cover stitching. Stick with established names that have a track record with the 911 community, and ask for samples before committing to a large order. Prices for a full rear seat upholstery kit (cushion and backrest covers) typically range from $200 to $600, depending on material.

Restoration and Installation Tips

Restoring the rear seats of a 1984 Targa is a manageable DIY project for anyone with moderate mechanical skill. The most common tasks are replacing the foam and upholstery, repairing or replacing hinges, and installing new seat belts.

Upholstery and Trim

Start by removing the rear seat assembly – it is held in with a few bolts accessible after folding the seat forward. Carefully separate the upholstery from the foam; original covers are often glued or hog-ringed. Replace the foam if it is brittle or disintegrating. Aftermarket foam comes pre-cut to fit the stock cover. When installing new covers, use the same method as the factory (hog rings or adhesive) to ensure a snug fit. For the targa, pay attention to the rear shelf carpet; it must be trimmed around the seat hinges and seat belt mounts.

Seat Belts and Hardware

If the original seat belts (lap belts) are worn, replace them with new ones from a reputable supplier. The mounting points are standard M10 bolts; aftermarket belts often come with the necessary hardware. For the seat hinges, clean and lubricate them with white lithium grease. If broken, used hinges are still available, or you can weld repairs on original ones. Do not skip replacing the seat belt brackets if they show rust, as safety is paramount.

Recommended Approach for Your Restoration

For most 1984 Porsche Targa owners, a mix of new reproduction upholstery and used original hardware delivers the best balance of cost, authenticity, and reliability. Start by ordering a seat foam and upholstery kit from a trusted aftermarket supplier, sourcing used seat hinges and brackets from a parts specialist, and purchasing new seat belts. This combination ensures a cohesive appearance without the high cost of rare NOS components. If you are aiming for a concours-level restoration, seek original Porsche parts through classic car dealers or swap meets, and invest in proper re-stitching of leather covers to match the factory grain.

Finally, keep in mind that the rear seat area is a niche part of the car – few people will scrutinize it as closely as the front seats or engine bay. Focus on structural integrity, fitment, and a color that matches the front interior. With careful sourcing and methodical installation, your 1984 Targa’s rear seats will look correct and last another three decades.
