Your Corvette's seat will not be complete until you remove the rusted spring that no longer has any give to them. You can do that with the C2 C3 Corvette 1963-1978 Seat Frame Spring.
This zig-zag seat frame spring will return your seat to feeling new, with the same bounciness and resistance it had when it was first made. The spring fits all Corvettes produced between 1963 and 1978.
Notes: These Springs Are A Heavier Gauge Than Original. They Need To Be Cut To Length And The Ends Shaped. They Work For 63-67 Bottoms And Both Back And Bottom For 68-78. Too Short For 63-67 Backs.
