1966 chevelle fiber glass hood replacement

My buddy and I recently replaced the hood of his 66 chevelle with a fiber glass one. It looks great but the only problem we are having is the hood isn't heavy enough to lay down correctly (I think) if you look at the hood from the fender side the center of the hood it is raised 1/4 of an inch when you close it. If you press down on the hood in the raised places it sits fine on the car (even when you drive it) it doesn't budge a bit until you open it and shut it. So with that being said I figured that since the hood is lighter lets change the springs to a softer set. this still didn't help but the hood closed easier. I don't think that changing the hinges is the way to go. besides I have heard the stories of replacing them and the tedious job of getting them to align properly. Any ideas?
Thanx
Ratt

Unfortunately the hinges are all the down on the forward side and all the way up on the rear side. I was thinking of making the holes on the forward side bigger to bring it down @ a lose for now.

try this

then i would try making the holes in the fender bigger not the hinges because the hinges are a much thicker metal and they are more expencive to replace then just to repare the fenders sheet metal where the hinges mount

The problem is probably with the springs that counterbalance the hood. They are still too strong and make the fiberglass bow. You can put even weaker springs, remove them altogether, or reinforce the hood. If the hood is bowing now in the winter, just wait until the summer. Those springs will have the hood 1" higher in the middle than at either end. If you put an unrelenting force (like a spring), on unreinforced fiberglass it will continue to move until you remove the force. It will move really fast in the heat. You can also try greasing up the pivot points on the hinge. Moving the front of the hinge down, if you can get the links to go even with or past center is a good idea. Hope this helps

Fiberglass is a composite of a plastic (usually vinyl ester resin) and an amorphous solid (glass fibers). By definition, both will "flow" under force. So not only are the springs causing an upward bow in the hood when it is closed, they are also making that bow semi-permanent. I say "semi", because you could remove the bow by placing an equal force on the hood for a like period of time and get it to return to close to the original shape. You would have to exactly duplicate the load and time to get the exact shape back, possible but not probable. I think Harwood and others make light springs to replace the stockers. Your best bet is to remove them altogether and use a prop rod.

Yup....take off those heavy springs before you crack/break your hood.

Race weight or street weight hood? Big difference in amount of reinforcing.
