2004 - XT - Will 2006 WRX Knuckle fit?

I was wondering if anyone knows if a 2006 WRX rear Knuckle/Hub will fit on a 2004 Forester XT. I trying to convert to the 4pot/2pot. I have looked around and but could not find part numbers for the knuckles to see if they are the same or not. Also I read some where that I might need to us a longer E-brake cable form the handle, but am not sure if that was just for earlier model Foresters.

Any help would be appreciated.
