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

I bought a set years ago from a seller over on Moparts. They still work great. I wish I could remember his name. I find hard to believe that there is no one out there making them.

It really seems like nobody is making them. I found a generic spring that looked like it could fit on Summit and I called their tech support to see if I could learn the specs. They said that it probably wouldn't work and that he would see if there was one made for our A-body application. I was on hold for 10 minutes and he came back with the "Happee Feelnigs" email address that he probably got from this forum.

I'll take a look over at Moparts before I do anything drastic :D
