03 tls - my tire and engine splash guards had to be ripped off one day on the side of the road. I probably left the screw/clips on the road as I was in a rush as I was pissed i had to rip them all off. Hit a bump racing on the highway at high speeds, they all got tangled and that was that meh.

I ordered the two below bumper clips, will I need anything else such as self tapping screws ect? I can't find much information on this repair, especially the under engine guard as I believe they're less common to be damaged.

The dealer said I would just need these below clips (tried to sell to me for $4 a piece lmao) and I have a hard time believing I can install all 3 pieces (2x tire 1x engine guard) with just these clips.
