Front rotor bolt pattern WR400 VS WR450

Hey guys

Im just wondering if the front brake rotor bolt pattern from a WR400(99) is the same as a WR450(06)

I know the sizes are different over the years but that is not concerns me. I'm purchasing a 320mm Disc for supermoto and have come across a cheap WR400 rotor.

Any help appreciated. :worthy:

The bolt pattern should be the same.
