Will a camaro hatchback fit on a 94 firebird?

i want to put a spoiler on my 94 firebird and if you look at it it already has a spoiler. the camaros look verry similar except without the spoiler. ive been curious as if it would fit on my firebird. i dont want the firebird spoiler on so i can put on a diffrent spiler. all i wana know is if it would fit without and fabrication. thanks
