My Outback 2003 H6 is missing the little "door" slider that opens the
little fiber door in the inside tailgate drivers side which gives
access to lights inside of the tailgate.

The parts man at my local Subaru dealer found it after looking on the
computer for 40 minutes.  I made him unhappy when I told him that $10
was too much to pay for it (I would grin and bear my Subie with a
missing part for that price but I would rather that she was complete.)

Is there someplace where I can get this less expensively?  (It is gray
plastic.)

Thanks
David
