Jen,

Try reaching up from below and running your fingers along the crack between
the bumper and the body, feeling along the inside bottom of the bumper. You
may be able to just remove it through the crack. Also, the bumper is not
all that hard to get loose/off if you want to get it over with.

It's in there somewhere, and yes if you ain't done it you ain't worked on a
Vanagon.

Jim
