Procedure

1. 1

   Remove Interior Door Trim Panel
   Remove the door pull handle by locating and removing fasteners. Remove any visible screws around the perimeter of the door trim panel. Use panel removal tools to carefully release the trim panel retaining clips working from the bottom edge upward. Lift the panel up and away from the door frame to disengage it from the window sill area. Disconnect any electrical connectors for power window or mirror switches before fully removing the panel.
2. 2

   Remove Interior Door Components
   Peel back the plastic vapor barrier carefully to access the door interior. Disconnect the door latch rod from the exterior handle mechanism by unclipping the rod from the plastic retainer. Disconnect any electrical connectors for door lock actuators or switches. Remove the window regulator mounting bolts and lower the window glass completely, then secure it in the up position using tape or blocks to prevent it from dropping during skin removal.
3. 3

   Remove Exterior Door Handle and Mirror
   From outside the door, remove the exterior door handle by accessing the mounting fasteners through the access holes in the door frame. Remove the door handle assembly complete with rod linkage. Remove the exterior mirror by removing the mounting bolts accessible from inside the door frame. Disconnect the mirror electrical connector if equipped with power mirrors.
4. 4

   Remove Door Weatherstrip and Moldings
   Remove the door weatherstrip seal from the perimeter of the door by pulling it out of the retaining channel. Remove any exterior door moldings or trim pieces attached to the door skin. Remove the belt weatherstrip from the window opening. Mark the position of any adjustable components before removal to aid reassembly alignment.
5. 5

   Identify Door Skin Attachment Points
   Inspect the door edge to identify how the outer skin is attached to the door frame. On the 1992 Viper, the door outer panel is fiberglass-reinforced plastic (composite), not welded sheet metal. The panel is bonded and/or mechanically fastened to the door substructure, so there are no spot welds or hemmed metal flanges. Do not attempt to drill spot welds; identify the adhesive bond lines and any mechanical fasteners instead. Mark all visible spot weld locations on both sides of the door frame perimeter using a marker or paint pen to track what needs to be drilled.
6. 6

   Drill Out Spot Welds
   The 1992 Viper door outer panel is a bonded composite panel with no spot welds. There is nothing to drill out. Instead, identify the adhesive bond joints and any mechanical fasteners, then plan for chemical/heat softening of the adhesive and careful mechanical release to separate the panel without cracking the composite.er, though exact count varies. Use a center punch to start each hole and prevent bit walking.
7. 7

   Separate Hemmed Edges
   The composite door panel is bonded to the door substructure with structural adhesive, not hemmed or welded. Soften the adhesive with appropriate heat and/or an approved adhesive-release tool and use plastic/composite separation wedges to gently work the panel loose. Do not use an air chisel, as it will crack the fiberglass. Take care not to damage the door substructure bonding surfaces, which must be reused. flange as it must be reused for the new skin.
8. 8

   Remove Old Door Skin
   With all attachment points separated, carefully peel the old door skin away from the door frame. Inspect for any remaining attachment points and separate them. Remove the old panel completely and set aside. Clean the substructure bonding surfaces thoroughly to remove all old adhesive using an approved adhesive remover and abrasion method suitable for the bonding flanges, taking care not to gouge the composite or damage the steel spaceframe.
9. 9

   Prepare Door Frame for New Skin
   Inspect the inner door frame for damage and straighten any bent flanges using body hammers and dollies. The flanges must be straight and true for proper skin fitment. Clean all mounting surfaces with wax and grease remover. Prepare all bonding surfaces per the panel adhesive manufacturer's instructions, including proper surface abrasion and application of any required adhesion promoter. No weld-through primer is used, as the composite panel is bonded rather than welded.
10. 10

    Test Fit New Door Skin
    Position the new door skin onto the door frame and check alignment at all edges. The skin should align properly with the frame flanges all around. Check that mounting holes for the exterior handle and mirror align correctly. Make any necessary adjustments to the door frame flanges before proceeding. Mark the position of the skin relative to the frame for final installation reference.
11. 11

    Install New Door Skin
    If using structural adhesive method: Apply panel bonding adhesive to the door frame flanges per adhesive manufacturer instructions. Position the new skin onto the frame matching your alignment marks. Use C-clamps around the perimeter to hold the skin in position while the adhesive cures. The composite door panel must be installed using structural panel adhesive per the OEM procedure; welding is not applicable to fiberglass. Apply the specified adhesive to the prepared bonding flanges, position the new panel to your alignment marks, and clamp around the perimeter until the adhesive cures per the manufacturer's specification.
12. 12

    Hem Door Skin Edge
    The composite panel has no metal hem to fold. Ensure the panel is fully seated and clamped along the bonded flanges and allow the structural adhesive to cure undisturbed. Do not attempt to hammer or hem the fiberglass edge. distortion in the door skin.
13. 13

    Seal and Finish Door Edges
    Apply body seam sealer to all edges where the skin meets the frame, including the hemmed perimeter and around any openings. Smooth the sealer with a sealer tool or finger to create a professional appearance. Inspect all bond joints for full contact and cleanly finish any excess cured adhesive. The door surface should be completely smooth and ready for body filler if needed.
14. 14

    Reinstall Door Hardware
    Reinstall the exterior door handle assembly through the door opening, connecting the latch rod mechanism and securing with mounting fasteners. Reinstall the exterior mirror with mounting bolts. Test the door handle operation to ensure proper latch engagement. Release the window glass from its secured position and reinstall the window regulator assembly with mounting bolts. Reconnect all electrical connectors for lock actuators and switches.
15. 15

    Reinstall Interior Components and Trim
    Install new vapor barrier or reuse the original if in good condition, ensuring it seals completely around the perimeter. Reinstall the interior door trim panel by connecting all electrical switches first, then positioning the panel and engaging the upper edge into the window sill area. Press firmly around the perimeter to engage all retaining clips, replacing any broken clips. Reinstall all trim panel fasteners and the door pull handle. Install the door weatherstrip seal into the retaining channel around the door perimeter and install belt weatherstrip in the window opening.

Reassembly

1. Reconnect the negative battery cable after all work is complete
2. The door will require complete surface preparation, primer, paint, and clear coat to match the vehicle
3. Allow any panel bonding adhesive to cure for the full time specified by the manufacturer (typically 24 hours) before painting or driving
4. Adjustment of door alignment, striker, and latch may be needed after skin replacement to ensure proper fit and operation

Verification

• Open and close the door several times to verify smooth operation and proper latching
• Check door alignment with adjacent body panels - gaps should be even all around
• Verify the exterior door handle operates smoothly and the latch engages properly
• Test power window operation if equipped to ensure no binding or interference
• Check that all interior trim panels are secure with no rattles
• Inspect all weld or bond points to ensure the skin is fully secured to the frame with no separation
• Verify weatherstrip seals properly around the entire door perimeter
