Front Valence Bar Attachment to Bumper Cover?

I'm replacing the plastic front end parts on a Gen 2 that was in a fender-bender accident that shattered the bumper cover and splash shields.

Could someone clarify for me the use of black U-shaped plastic fasteners on the lower plastic bar known as "The Valance" in some explosion diagrams? In other diagrams this long, thin plastic part is known as "the lower spoiler". It contains two rows of perforated tabs.

In this posting I'll call the long thin part The Valance.

It appears that four things terminate on The Valence:

• the left side under motor splash shield
• the right side under motor splash shield
• the center under motor splash shield
• the bumper cover

I know that stuff terminates on The Valance with collection of U-clips with #14 threaded bolts through them. It appears that the left and right side splash shields overlap each other at the center, anchor to a metal radiator support bar with M6 bolts, and then anchor with U-clips to a row of tabs on The Valance.

So far, so good, but I'm choking on what comes next.

How does a second set of U-clips manage to anchor both the bumper cover and center splash shield to The Valance? These U-clips are fairly large but it seems there isn't enough space in the U-clip's jaws to squeeze all of this plastic at once.

Is it possible that the bumper cover's lower edge is merely hooked to the U-clips rather than being squeezed by the clips' pinched jaws?

I need to disassemble another Gen 2 to fully understand this. Too much stuff is landing on The Valence, and I'm distracted by Toyota's strange choice to have the side splash shields covered by a redundant center splash shield.

 

I've mis-described the assembly sequence above. The right and left splash shields are sharing the same U-clips as the bumper cover tabs, not the center shield.

The redundant center splash shield alone terminates on The Valance's bottom row of tabs.

So my challenge is to understand how the upper row of U-clips is able to deal with the bumper cover, both right and left splash shields, and The Valence--all at the same time.

 

Never mind. I got this figured out. The correct clips attached to the bumper cover are not U-clips but S-clips. The distinction is that the black S-clips have two slots in them facing in opposite directions.

One slot in the S-clip accepts the tab on the bumper cover. The other slot in the S-clip accepts the right/left splash shields.

The white U-clips are used to secure the center shield to the bottom row of tabs on The Valance.

Thanks for letting me ramble on this.
