Wings: Bottom skins. ADAHRS mount.

I have to redo the ADAHRS mount.  Looks like the mount slipped when I was match drilling to the J-stiffener, so it didn't fit properly after I riveted the whole thing together.  This caused the J-stiffener to bow a bit.  Bummer.  Interestingly, the tray shipping from Van's is now sans tab.  See the first ADAHRS post to read about that tab.

Original ADAHRS mount on top.  New on bottom.
