HEllo, i was wondering about the exterior lower plastic strip "door ground effect" that goes along the length of the door. Mine is a bit loose . Should there be some kind of retainers on the "peg" that holds them on better ? What would i need?

 

Yes. There should be other studs on that trim piece that pass through the door. Look at those for an example of the nut that holds it.

 

No nuts on the other studs.

 

How about the other door? Lol

any of the other trim on the car? All the ground effects nuts are the same if I remember correctly. Except for the front chin piece.
