How do you know if your springs are too strong for your fiberglass hood?

This is on an A-body, right? You can't just pop hood springs on and off, cause they're down under the fender! Somebody here makes light springs to replace the originals - I got them for my race car 6-8 years ago but can't find the info.
K-Cars, most likely.

Found him. Not his screen name you will have to email. Dennis has the lower tension hood springs for A Bodies. Just ordered my set yesterday for my 67 Barracuda!!

Tossing your stock springs in a fire for an hour will probably create you some nice low-tension springs.
