I'm attaching a photo of the back side of one of my quarter interior panels. These are older legendary brand (at least 6 years). The holes for the clips are these perforated rectangles. do they just pop out like I've done with one or am I missing something. There's no double wall cardboard and a pocket the clip goes into like I would expect. Seems weird to have holes all the way to the foam. The ones shown in the instructions on the Legendary site are different. Anyone have this style or know to install the clips?
