DD, I am sure someone will beat me to the punch, but I just bought three Duster parts cars. When I start to dismantle I will let you know what I see. I pulled down the cardboard one out of the Demon and small c-shaped clips held the liner to the backboard. It all snugged up under the roof line trim. The C Pillar or Sail portion was separate. Mine was disintegrating so I trashed it. I found some ABS replacements, but I can't tell you about quality or fit, not there yet.
