There's no chance to simply buy a new one. Maybe you can get it after sending them the old one, but you should ask CS about that. Even if that's possible I'm 100% sure you can't get a black one - you can only get parts that a guitar came with originally (i.e. my JP7 BFR has nickel frets and it would get nickel frets after refretting at EB even though this model comes with SS frets now).
