By the looks of it, the two sets of ears are for whatever type of helmet you're building, stunt (four bumps) and hero (three bumps).
I should hopefully receive my ATA helmet soon to replace the abomination I'm using. (FX, its horrible)
That's the thing though, I know someone who used to work in the shipping business and he says when something is marked as fragile they throw them for fun.
Anyway, it's good to see nothing was damaged. Good luck and have fun with the build.
If you have a Flickr account you could upload there then post either the links, or by using the BBCode.
You don't have to use Flickr, could use Photobucket or any other picture hosting service you prefer.
