does any one know the difference in weight between the pre 84 z28 hoods that were fiberglass and a later steel one?

 

I have both hoods, my firgerglass one is off and bare. I could weight it sometime. My steel hood is on a parts car 25 miles away. I'm going to guess the difference is very, very small. The metal hoods are built very light. The glass hoods have some meat to them.

 

Thanks, i was doing some reserch and saw those had fiberglass hoods and was wondering if it was a good weight saver
