Correct.
Both springs are unique to ZR-1's.
Some were removed by those that changed to Coil overs and may be floating around.
If safety is a concern, and it should be, get any of the C-4 springs that are even remotely close to the rate of the ZR-1 spring.
Refer to Hib's chart at the Corvette Action Center
If judging is the concern do not dispose of the code tag from your existing spring, as that likely will be the only way to evidence a "correct" one.
These springs typically fail from the vehicle being tightened with a strap too aggressively when on a flatbed or a trailer.
The spring is not robust enough to handle being flexed the wrong way in those situations.
I have never found a new correct ZR-1 replacement spring.
But, things change.
Good luck!
Marty
