In today's episode, we're in the fab shop at V8 Speed and Resto fabricating a custom firewall for a 1979 Pontiac Trans Am. The goal is to address rust issues, fix previous damage, and enhance the overall appearance under the hood.
The original floorboard replacement didn't extend high enough to fully cover the rust, and the factory stamping had some unappealing imperfections. We decided to cut out the affected area and create a more visually appealing piece that complements the car's aesthetics without altering the entire undercarriage.
Key Points:
Material selection: 20-gauge sheet steel for its strength and workability
Step roll pattern: Adds strength, creates a visual break, and enhances the industrial look
Bead rolling technique: Using the Mittler Brothers bead roller to create a custom pattern
Panel preparation: Pre-stretching the metal to prevent distortion during bead rolling
Electric bead roller: Variable speed and forward/reverse operation for precise control
Corner shaping: Addressing shrinking and stretching around the pattern corners
Edge rounding: Using a Pullmax with radius dies for a smooth transition to adjacent panels
Panel installation: Utilizing magnets for flush fitment and clamps for secure attachment
Welding: Tack welding, seam welding, and grinding for a seamless finish
Additional Notes:
Rust prevention: Applying rust-resistant primer and paint to protect the new firewall
Wiring and hoses: Accommodating future wiring and hoses without compromising the visual appeal
Overall design: Maintaining a cohesive look with the rest of the under-hood components
This custom firewall project demonstrates the importance of careful planning, precise fabrication techniques, and attention to detail when restoring classic vehicles. By addressing rust issues, enhancing the appearance, and ensuring compatibility with future modifications, we're contributing to the preservation and enjoyment of this iconic Trans Am.
