Crayon

I'm replacing one currently (some a-hole backed into my parked Z and cracked it). The spoiler comes in three parts, which should be individually removable.

Edit: It comes as a base, that vertical middle piece, and the top wing, for reference. I'll have to give it a look when my new one comes in, but I believe the top wing is secured via the base, through some mounting bolts. I could be wrong, but that's what it looks like at the moment.
