Spear I applied the tape extremely light to the clips when I went to align the CF B-Pillar... Once I got that aligned I pressed the B-Pillars somewhat firmly but not too much and peeled the B-pillar like in the video. when that happened the tape stuck to the B-Pillar and not the clip leaving me accurate placement to glue the clips to.
In regards to stock removal... the Stock pieces have built it plastic pieces that allow the clips to lock into. However the openings point toward each other only allowing you to pull the B-Pillar out to remove it. I recommend getting a screw driver *BE CAREFUL* and as you begin to pull the B-Pillar work the clips out. Take your time cause the brackets on the back of the B-Pillars are cheap and will break easily.
I hope that helps
