I've been having a real hard time finding the upper trim molding that is on the outter upper edge of the front fender (left side). The previous owner had the front end repainted and it looks like whoever re-assembled everything did a crap job and so some clips weren't re-used and the molding flew off when my wife was on the highway the other day. I can't find the part number for it anywhere online. Any ideas?

Hey, that's pretty close! That looks like the part number for the rear one. Do you know the one for the front left?

I don't but it should be one of those. Call the dealership and see if they have the breakdown for the location of each part.

Ended up figuring out the parts I needed.

166-884-61-22-5890 is for the left front fender molding that is painted the body color. The 5890 on the end designates that it's pre-painted lunar blue which is the color I needed. If you want just the plastic piece and you want to get it painted somewhere, change 5890 for 9999 and that's it.
166-884-63-22 is for the left front fender molding mounting bracket which the molding attaches to. It is what secures to the actual fender with some 3m double sided tape, and then you snap the fender molding onto it.

The other way to search is to eliminate the dashes -
