You have to remove both the scuff plate and the header at the rear of the van. Using a 9/16 socket, undo the upper seatbelt bolt next to the window. From the bottom of the 'D' pillar (interior panel) gently pull it an inch or so away from the side. There are 3 plastic push-pins holding the pillar to the body so use a long pair of needle-nose to wiggle them out. When they are out wiggle the pillar back and forth to release the last clip at the top of the pillar. I hope this helps you out.
