I just got home and took apart my brakes to put new rotors on and as I'm reaching for the box I notice they gave me FD rotors. Grrrrr...

I know the calipers aren't useable... What about the rotors? I don't really wanna put all this back together, drive down the the parts store, gripe at them, order new one's, and then have to take it all apart later this week.

Thanks
