Structural Underbody Support for Seat Track Installation

Designed to match original specifications, this stamped steel support sits beneath the seat track and anchors to the floor pan—ensuring your seat adjusts correctly and remains securely mounted.

If you're restoring a C1 Corvette or repairing fatigued floor structure, this often-overlooked support is critical for safety and correct seating geometry.
