Bolt Removal Note
WARNING: This page is about a different car, the 2004 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Bolts or tools dropped into the A-pillar are difficult to remove. To prevent this, roll regular paper into a tube. Insert it into the hole, and hold it so that it does not move when performing the work.
