1956-1957 C1 Seat Belt Inner LH Underbody Reinforcement
Restore Structure Where It Matters Most
If you're planning a body-off restoration or revisiting an earlier build, don’t overlook the original seat belt underbody reinforcements. These critical support pieces were factory-installed to help protect the Corvette’s fiberglass body by distributing seat and belt forces across reinforced mounting zones. This 1956–1957 Corvette Driver Side Underbody Reinforcement restores that vital structure with an exact reproduction of the early-style plate used before seat belts were standard.
Features
• Authentic stamped steel construction
• Mounts beneath driver seat location
• Reinforces inner floor pan at belt area
• Welds or rivets in place like original
• Essential for early C1 structural integrity
Fitment
• 1956–1957 Corvette (Driver Side)
• Correct early version for cars not factory-equipped with seat belts
Because Details Matter
Early C1 Corvettes lacked modern restraint systems—but GM still reinforced the floor structure for strength and safety. This reproduction returns that factory-correct rigidity to your restoration without introducing incorrect later-year features.
