Went to the dealer today. Told them about the missing parts. He said there could have been a running change to what parts are used from year to year, mentioning the missing engine cover as an example. I told him that fiasco caused me $150. to install the engine cover on my own. I said that while the engine cover deletion is really just for aesthetics, the missing wheelwell/fender parts are more related to a structure deficiency.
Anyway, I showed him the pictures of what my fender wells looked like and showed him the pictures that Sharbotcom, the OP provided with the added parts. He went to the parts department and came back stating there were no parts showing in the system. Alas, once again, I pulled out the screenshot of the part numbers again provided by the OP. He went back to the parts department and came back saying that the parts are now ordered and he will contact me when they come in. I will update when the parts are installed.
A big shoutout to Sharbotcom for all the information he provided.
