A couple months ago, a bolt suddenly appeared on the passenger
side carpet of my 97 Civic HB, under the dash. Now I have developed a
noticeable rattle somewhere around the glove box when I go over
a big bump. Even when I empty the junk out of it! :-)

The bolt is black, hex headed, about an inch long, and has a
lock washer and a flat washer on it. Before I try and squeeze
myself under the dash to take a look, has anyone else had
this happen? Any hints on where to check first? Thanks.
