Thanks to everyone for your replies and suggestions. I ended up removing the fender liner and clips, and noticed that where the sheet metal meets the plastic bumper cover, the lip on the metal was pulled forward. The alignment pin on the bottom edge of the cover, as well as on the top, were in place. So, I took a shop towel and folded it a few times and held it onto the lip. I then swung a 3lb hammer and started to bang the edge back in. The sheet metal was much stronger than one would think, so I had to swing pretty hard. Probably a good 25 swings. It did improve the overall appearance of the fender/cover joint. Not factory perfect like the other side, but that's alright. The only thing is, on one of the harder swings it glanced off the edge and put a not too deep scratch in the paint, even through the shop towel. There was also a crack in the paint where I was hitting it, which is hard to see. I'd probably use a denser material to protect the fender if having to do it again, though. Overall, the job was worth it. If I can ask, what would a pro have done in a similar situation? Would he hit it with a similar type hammer or is there another way/method to use to do the job professionally? Also, if anyone can recommend a fastener kit for this particular vehicle, 2013 E350, I'd appreciate it. Thanks again.
