Quick brake disc help please

[Rip_Tear]

So I need to order a new rear disc brake, but I can't find one... Is it the same as one of the front brakes? or the same as a 450R or 400EX brake?

Thank you

Bump...

Someone's got to know!?

huh???? Rockymountain sells them as a tusk brand, Braking sells them in wave and standard, Ebc sells them in both styles and probably more.
