GM lists two front springs for the 1970 Corvette, one for the 350 and one for the 454...
VIK; page 109

When you get some time, check out the Vehicle Information Kit for you car here...
https://www.gmheritagecenter.com/doc...t-Corvette.pdf
It is filled with all sorts of information you will find useful regarding your Corvette.

You can also check out this thread, post #4 for some additional part numbers...

Good Luck... GUSTO

Grant, GM lists two front springs for the 1969 Corvette as well, one for the 350 and one for the 454...
VIK; page 117

Interestingly, the specs appear to be the same...

However... The part #s changed (according to the GM parts wiki):
3931823 changed to 331316 in Nov. '72
3931825 changed to 331317 in Jan. '73

Also according to the parts look up, there were apparently no other GM products using these parts.

Check with Zip products. They have exact replacements with the narrow spaced coils on the top.
