The fun begins where the B-pillars end. Beneath their lower cover panels, the side flaps' cables and straps are accessible. Also, these trim pieces need to come off in order to remove the rear panel, behind the seats. Then the quarter-window components can be removed and replaced as necessary.

Removing the metal plates and plastic covers at the base of the B-pillars isn't difficult. The hardest part is probably corralling the hardware: the metal plates' screws are tiny, and the screws in the seatbelts' shoulder openings can easily disappear down voids behind the seats.

The photos illustrate the process. Assembly reverses the removal steps.

The metal plates attach to the body with three small screws (arrows).

The plastic panel has a Phillips screw in the shoulder belt slot.

Opening the top creates wrench room for the bolt that secures the plastic panel at its rear (arrow).

Comments and Suggestions:
Brownfield Comments: When removing the 8-mm bolt figure 3, what happens to the square metal nut on the other side? Does it remain attached to the plastic cover?

  Followup from the Pelican Staff: I believe it is a welded nut. - Nick at Pelican Parts

  Followup from the Pelican Staff: The trim panels should be held on with trim panel clips. Use a trim panel tool to remove them. - Nick at Pelican Parts  
AZAFVET Comments: I am trying to replace the hydraulic lines for the front locking cylinder and am having a hard time removing/installing them at the rear pillar. Not sure how to access them and have a suspicion that there is a tie wrap holding the lines together and making any attempt to pull them through the pillar impossible. I am so close to being finished!! Any ideas?
