Has anyone had a problem with their hood manufactured after 1980? I was going to add braces to mine at one point but since the kits are listed as 73-80 it seems GM fixed the problem for '81 and later.
After 1980 they changed the hinges, and they don't seem to cause the hood to bend like the earlier ones.
I'd never heard about the "intentional fold in a crash" component. That may be true, but the things crumpling in use has always aggravated me. I try to keep the hinges well lubed. I've never added stiffeners, but now I'm thinking about it.
Yes, the hood is designed to fold in a crash, keeping it from going thru the windshield and injuring the passengers. Keeping the hinges lubed helps, but they still tend to bend if you are not careful. There was post a while back about a body shop that was sued because they didn't fix a roof on a small car properly, and it didn't fold like it was supposed to during a crash, and the occupants were injured.
I'm also thinking of using the LMC kit when I replace my hood, if I can't find anything else. I don't think it would be too stiff to keep the hood from folding in a crash, but should keep it straight under normal use.
I have seen people use angle iron and such (my current truck, but not my doing), but I am afraid that would be too stiff in a crash.
