New take off drivers side mirror glass for the 2004-2006 Pontiac GTO.  We sourced these from a supplier who used GTO mirror assemblies to convert the mirrors to the correct spec for RHD based GTOs (Monaros).  The housing is the same between the cars but the curvature of the glass is different which is why they were replaced.   These will come in an OEM GM box but will NOT have the correct part number as the boxes came from the glass that was installed.  The part number we have listed is the correct part number for the glass.
