Thanks for the response. I messed around with it tonight and eventually found success. I had to loosen the molding that runs between the bumper and the headlights (it's about an inch wide). To get to some of the screws, I had to remove the side running light assembly (2 screws). By loosening this molding, I was able to insert a flat bladed screwdriver under the headlight and pop off the black insert that holds the headlight to a post. There are two more of these that are accessable from the top, but it was this bottom one that had me stumped. Not any more!
Thanks for your help...I'm sure I'll need more.
