What to do with all of the junk.

I really do need to get around to getting my yard sale up and going at some point, I have so much freaking junk that I need to get rid of.
Half of it, I don't even know where it came from.
I was going through some stuff in my room the other day, and I came across a rear spoiler or light cover thingy for a Ford Mustang.
Where the heck did I get that?!
I have no idea, I don't own a Mustang, heck, I don't even own a car.
I am going to do the yard sale at some point before the summer is over, and that car part is going in the yard sale unless one of you readers needs a light cover thingy for your Mustang.
