400ex/450r Front rotor interchangeability?

[Burns310r]

Are the front brake rotors interchangeable on these hubs. Im pretty sure they are along with the hubs.

I just smoked an entire hub on my 250r (running 400ex spindles) and it took the rotor with it.

I need to find a rotor asap, and it would be easier if i knew that it didnt matter if it was a 400ex or 450r.

Thanks
