i have yet to see an aluminum one and the only thing other than steel on any third gen anything i have ever had/seen was an 83 z28 l69 700r4 with fiberglass stock z28 hood but one corner was busted on it.
all the firebirds including my lg4 82 regular trans am have had steel flat or p/g hoods.
my 82 gas engine car has non functioning PG with the honeycomb screen in it and no other parts on or below it
the 82 lg4 regular trans ams were this way and the most common ones sold
have an aluminum hood on our 01 aurora and omfg!!! its light like a feather, crazy.. really., its really odd feeling to pick it up and not weigh anything at all haha
i unbolted it while we replaced the transmission in the car, so i could overhead crane hold up the engine so i could drop the entire cradle from under the car and let the engine down some to get the trans out
