Photos of changing the grommets (it is best to push them in rather
than trying to pull them out.)
This is one of the black rubber things that the door panel anchor push
into. I wanted to remove them so I could get the vapor barrier installed
nice and neat.
I tried pulling the grommets out, and I tried pushing them out from
the inside of the door. No go.
What worked was what this photo shows: push them into the holes.
