How do you install the cross rails to the roof rails on a 2010 RX 350? Chuck

Unfortunately a turkey flew up out of a ditch today breaking the passenger side outside mirror on my 2001 RX300. The painted housing is ok, but the mirror and inside mechanisms are damaged beyond repair. I need to get the whole assembly off to replace the parts, how do I get it apart? Do I have to remove the inside door panel, if so, any special tools required?
