ok, so I took some pics



So what happened to me is the lower part of the metal just bent forward on me. Which let the whitish plastic piece just come out. Its a tight fit, so I bent it further forward to help me guide the plastic peice back in. After getting it back in I bent it back (and then a little bit further) into place. What you may be able to do is just unscrew the bracket, that might make it even easier to get back in.
