So, I do not have a pic of before and after on my GV80 - just after. But this is what I'm referring to:
Lower inside trim that is removed [it's held on via plastic clips] and ---->

---> is replaced by a trim piece that is part of the board assembly. This is so you can access the factory mount points for the boards [original trim removal], install some of the hardware that holds the boards; thus covering the mounts again and retain the door seal between the new trim piece and the boards.

At 1st I thought it was a little too much black plastic as the other trim piece is matched to the vehicle color, but this only shows when the door is open so I quickly got over that. I may get that the lower B-pillar body stainless steel cover you see in the 1st photo, just to beauty that area up if it bothers me again.
