I hope you picked the tail lights from the Caprice. I believe you mean the C pillar exterior door trim, because there is no B pillar trim. Did you get any rear grab handle light lenses? There are a lot of hard to find parts you can pull. You can even finance your trip with some of them. Electric antennas that are not bent, Driver door panels, gate glass solenoids, driver's side front arm rest (caprice) and rear wiper arms.
