The piece from the back bumper to the Wheelwell, looking inside the trunk its held on by 4 clips.

They look like the type of clip that you would use a pliers on to squeeze the prong like clip ends together and then push out.

Is this the way to remove the trim piece ?

And then how do you go about putting the trim piece back on the car? can you reuse the clips?

Thanks a bunch

If the clips are original thay should be white color the molding snaps on to remove pry off gently. The clip is held to the body with pin pushed in the center spreads out fingers in the hole in the body. As far reusing as long as the clip is not had and cracking
