1970–1978 Corvette C3 Seat Back Release Button | GM# 3976505
Get your seat function back in style with this 1970–1978 Corvette C3 Seat Back Release Button, an exclusive reproduction of the original GM part number 3976505. Designed for seamless form and function, this button restores full adjustability to your C3's bucket seatbacks—without sacrificing authenticity or appearance.
Restore Movement. Reclaim Comfort.
When your seat back won’t release, it’s not just annoying—it’s limiting. This release button brings back the smooth, factory-correct operation that Corvette owners expect. Whether you’re detailing your interior, repairing tired hardware, or building a show-quality restoration, this is one of those details that makes all the difference.
Crafted to OE specs, it installs easily and performs just like the original, helping your seat tilt forward with a press—just like it did on the showroom floor.
Why It’s Important: The seat back release button isn’t just for convenience—it’s a key part of accessing the rear cargo area and ensuring safe seat adjustment. A broken or missing button throws off the usability and appearance of your C3’s cockpit.
