Sorry for a delay at getting back, but things are a bit busy.
Yes it is a wire/rod that runs the length of the fender edge roll. About the size of welding rod. Both fenders have this. I would imagine that it is there to support the shape of the fender. Seems if it was not there that the fender would be a bit flimsy and easily bent. I have added 5 close up photos to show what I am talking about. http://s111.photobucket.com/albums/...action=view&current=Untitled-5-1.jpg

The metal is not overly stretched, I just want to get the bend out of the wire. Apparently who ever did the body work originally just slapped bond-o there to make the curve look right, but was pretty thick. I have been doing body work on and off for many years. For myself and professionally, mostly motorcycle crash repair. So I am not totally inexperienced.
