So I replaced my bumper with a reproduction bumper and the heavy metal piece under the bumper is partialy exposed now any ideas? I have attached a photo.
Years ago there were some aftermarket bumpers being sold that had too much of a bend in them which left a big gap in the center of the bumper similar to what you show in your pic. I don't remember who was selling these bumpers and I don't know if this is still an issue with aftermarket bumpers.
