Do you mean the outside trim that is kind of the extension of the bumper?  If
so, lay down in the driveway and look up at the trim. There are nuts up there
 attached to carriage bolts. So all you need do is remove the nuts. I think
the  nuts are 10mm.  Then the trim "unhooks" off the car if you lift the piece
toward the sky.

Hope this helps.

I'm  trying to remove the fiberglass/plastic trim panel at the
bottom/front (in  front of the door) on my '90 Westy but can't figure
out how it is  attached.  Before I start ripping things apart out of
ignorance, how  is the damn thing attached and how do I get it off for
painting and then  replace?
