How To Turn Bucket Seats Into Bench Seat

The allure of a classic bench seat, offering space and a touch of nostalgia, often clashes with the modern prevalence of bucket seats. Swapping buckets for a bench is a modification often considered for vintage trucks, classic cars, and even some modern vehicles where owners prioritize a different seating arrangement. While not a bolt-in affair in most cases, understanding the key considerations and steps involved can make this conversion achievable.

Assessing the Feasibility: A Foundation for Success

Before diving into the practicalities, the most crucial step is determining if such a conversion is even feasible for your specific vehicle. This involves a multi-faceted assessment:

Measuring and Space Evaluation: The Crucial First Step

Carefully measure the width of the cabin floor between the door sills. This provides the maximum width available for a bench seat. Then, measure the distance from the dashboard to the back of the current bucket seats at their rearmost comfortable position. This determines the maximum depth available. Compare these measurements to the dimensions of potential bench seat candidates. Remember to factor in any floor-mounted consoles or obstructions that might interfere.

Structural Integrity and Mounting Points: Ensuring Safety

The original bucket seat mounting points are unlikely to align perfectly with a bench seat. You'll need to assess the existing floor structure for its ability to support new mounting points. The floor must be structurally sound, free from rust, and thick enough to safely accommodate the force exerted during braking or a collision. This is where professional welding or fabrication may become necessary. Reinforcement plates may be required to distribute the load properly. Check for existing holes or depressions in the floor that might suggest previous seat mounting locations. These could offer a starting point for new mounts.

Seat Belt Considerations: A Critical Safety Component

Seat belt mounting is a critical safety aspect. Determine if the bench seat you're considering has integrated seat belts or if you'll need to reuse or relocate the existing belts. The factory seat belt anchors must be in good condition and properly secured. If relocating, ensure that the new mounting points comply with safety regulations and are structurally sound. Using factory seat belt mounting points whenever possible is the safest approach. Consider the angle and reach of the seatbelts – they must properly restrain occupants in all seating positions. For older vehicles, consider upgrading to modern three-point seatbelts for enhanced safety.

Steering Column Alignment: A Factor Often Overlooked

In some vehicles, particularly those with offset steering columns, a full bench seat might cause discomfort or restrict the driver's legroom. Carefully assess the position of the steering column relative to the proposed bench seat. Consider the driver's height and build to ensure adequate legroom and comfortable reach to the pedals and steering wheel. An adjustable steering column can help mitigate minor alignment issues.

Sourcing a Suitable Bench Seat: A Treasure Hunt

Finding the right bench seat can be challenging, but several avenues exist:

Salvage Yards: A Goldmine of Possibilities

Salvage yards are a prime source for bench seats from various vehicles. Measure the seats of several candidates and carefully inspect for wear, tear, and structural damage. Seats from similar-era vehicles often require less modification. Look for seats from vehicles with similar dimensions and styling to your own. Don't overlook seemingly unrelated vehicles – you might find a seat that, with some modification, fits perfectly. Carefully inspect the seat frame for rust or damage before purchasing. Negotiate the price, as salvage yards often offer some flexibility.

Aftermarket Options: Customization and Modern Features

The aftermarket offers universal bench seats, often with improved comfort and safety features. These seats typically require some fabrication and installation work. Choose a reputable brand that meets safety standards. Aftermarket seats often come with modern features like reclining backrests and adjustable headrests. Consider the upholstery material and color to match your vehicle's interior. Pay close attention to the dimensions of aftermarket seats to ensure they fit your vehicle's cabin.

Custom Fabrication: A Tailored Solution

For a truly custom solution, consider having a bench seat fabricated. This allows for precise fitment and personalization. However, it's the most expensive option. A skilled fabricator can create a seat that perfectly matches your vehicle's interior and your specific requirements. This option is ideal for vehicles with unusual dimensions or those requiring a specific aesthetic.

The Installation Process: A Step-by-Step Guide

Installing a bench seat involves careful planning and execution. Safety should always be paramount.

Preparing the Cabin: Clearing the Way

Remove the existing bucket seats and thoroughly clean the cabin floor. This will allow you to assess the mounting points and identify any obstructions. Disconnect the battery before starting any electrical work related to seat sensors or airbags. Remove any debris or loose wiring from the floor. Use a degreaser to clean any grease or oil spills. This will provide a clean surface for welding or drilling.

Creating Mounting Points: The Foundation of Security

Position the bench seat in the desired location and mark the points where it will be mounted. If drilling new holes, ensure they are properly aligned and reinforced. Welding mounting brackets is generally the strongest and safest option. Use backing plates to distribute the load and prevent the floor from tearing. Ensure the welds are strong and properly penetrate the metal. Protect surrounding areas from weld spatter to prevent damage. Always use proper safety equipment, including a welding helmet, gloves, and a respirator.

Seat Belt Integration: A Non-Negotiable Safety Feature

Connect the seat belts to the bench seat or the existing anchor points. Ensure the seat belts are properly adjusted and provide adequate restraint. Verify that the seat belts are not twisted or obstructed. Test the seat belt locking mechanism to ensure it functions correctly. If necessary, consult a professional for seat belt installation or modification.

Final Adjustments and Testing: Ensuring Comfort and Safety

Once the seat is installed, make any necessary adjustments to ensure it is comfortable and properly aligned. Test the seat for stability and ensure that it does not wobble or shift during driving. Double-check all mounting bolts and seat belt connections. Take the vehicle for a test drive to ensure the seat is comfortable and does not interfere with driving. Have a passenger sit in each seating position to check for comfort and adequate legroom.

Potential Challenges and Considerations: Anticipating the Roadblocks

Converting bucket seats to a bench seat can present several challenges:

Floor Pan Modifications: A Common Hurdle

The floor pan may require modifications to accommodate the bench seat's mounting points. This can involve welding, cutting, and fabrication. A skilled metalworker or fabricator is recommended for this task. Rust repair may also be necessary if the floor pan is corroded. Ensure that all modifications are structurally sound and meet safety standards.

Electrical System Integration: Addressing Seat Sensors

Modern vehicles often have seat sensors and airbags that must be properly integrated with the new bench seat. This may require rewiring or reprogramming the vehicle's computer. Consult a qualified automotive electrician for assistance. Improperly integrating seat sensors can trigger warning lights or disable airbags. Consider disabling the airbags altogether if you are unsure how to properly integrate them with the new seat.

Legal and Safety Regulations: Ensuring Compliance

Ensure that the bench seat conversion complies with all applicable legal and safety regulations. This may involve inspections and certifications. Check your local laws regarding seat belt requirements and modifications to safety equipment. Consulting with a qualified mechanic or automotive engineer is recommended to ensure compliance.

Conclusion: A Rewarding Transformation

Converting bucket seats to a bench seat is a complex but potentially rewarding modification. Careful planning, meticulous execution, and attention to safety are paramount. By understanding the key considerations and following the steps outlined above, you can successfully transform your vehicle's interior and enjoy the classic comfort and space of a bench seat. However, if you are not comfortable with welding, fabrication, or electrical work, it is always best to consult with a qualified professional.
