Today we fit 5 brandy-new Hankook RA08s, and whilst I was up
underneath with the spare tire carrier opened, I repaired my floppy
passenger side air dam.

  Two nuts had come unwelded, so I cut off the screw heads, drilled
new holes adjacent to the original mounting points, and refastened the
piece using washered sheet metal screws.

BTW, you can still read a realtor's partial telephone number on the
sheet of stick into the ground plastic sign material that serves as a
lower air duct between the grille & rad. (bottom piece, parallel to
the road)   I fashioned it a few years ago and can vouch for its
tenacity.
