Procedure

1. 1

   Remove rear wheel arch liner and inner fender components
   Working from inside the wheel well, locate and remove all fasteners securing the rear wheel arch liner. Remove the plastic push clips along the front and upper edges, then remove the screws along the lower edge. Carefully pull the liner away from the quarter panel, noting any wiring harness routing clips attached to it. Disconnect any wiring for side marker lights that may route through this area.
2. 2

   Remove taillamp assembly
   From inside the trunk, locate the taillight assembly mounting nuts (typically accessed through trunk liner or service panel). Remove the mounting nuts securing the taillamp housing. Disconnect the electrical connector by pressing the release tab and pulling straight back. Carefully remove the entire taillight assembly from the quarter panel and store in protected location.
3. 3

   Remove trunk interior trim panels
   Remove trunk side trim panel on affected side by locating and removing all fasteners. These may include plastic push clips along upper edge and screws along lower mounting points. Carefully pull trim panel away to release any remaining clips. Remove carpeting or trunk liner material from quarter panel area to expose inner structure. The Viper trunk trim is typically multi-piece construction with separate side panels and rear bulkhead sections.
4. 4

   Remove fuel door assembly and external trim
   From inside the trunk area behind the quarter panel, locate the fuel door release mechanism and mounting hardware. Disconnect the fuel door cable by releasing the cable end from the latch mechanism. Remove the mounting screws or bolts securing the fuel door hinge assembly. From exterior, remove any quarter panel moldings, side marker lights, and badge emblems using appropriate trim removal tools. Heat gently with heat gun if adhesive-mounted.
5. 5

   Remove rear bumper cover
   Remove fasteners securing rear bumper cover to quarter panel area. This includes screws in wheel well area, fasteners along top edge near trunk opening, and lower mounting points underneath. Disconnect any wiring for license plate lights or parking sensors. With assistance, carefully pull bumper cover away from quarter panel tabs and remove from vehicle. This provides access to quarter panel-to-bumper mounting flange.
6. 6

   Document body dimensions and alignment points
   Using body dimension gauge and measuring tape, record critical dimensions from known reference points to quarter panel mounting locations. Measure diagonally from opposite side suspension mounting points to quarter panel edges. Record door-to-quarter panel gap measurements at three points (top, middle, bottom). Measure from rocker panel to quarter panel lower edge. These measurements are critical for aligning replacement panel. Take photos with measuring tape visible.
7. 7

   Mark quarter panel cut lines
   Using the replacement panel as template, identify where factory spot welds and seams connect quarter panel to body structure. Typical cut locations include: along rocker panel seam, at rear body panel vertical seam, at wheel arch opening inner flange, and at trunk opening flange. Mark cut lines with felt tip marker or scribe, staying approximately 1 inch away from structural mounting flanges to preserve spot weld locations for new panel. Verify cut lines will not intrude on adjacent panels (door, roof, or rear fascia mounting areas).
8. 8

   Remove spot welds along quarter panel mounting flanges
   The 2008 Viper quarter panel is a composite (fiberglass/RTM) panel bonded and bolted to the tubular spaceframe — it is NOT spot-welded. Do not attempt to drill spot welds. Instead, remove the mechanical fasteners securing the panel to the frame and carefully release the structural adhesive bond lines per OEM composite panel service instructions. Drill only through outer panel layer, not through both layers of metal. Use air chisel with panel separator to carefully separate seam sealed joints along rocker and rear body panel after spot welds are removed.
9. 9

   Separate and remove damaged quarter panel
   With all spot welds removed, use body panel spreaders to carefully separate quarter panel from inner structure at remaining adhesive-bonded areas. Work slowly to avoid distorting inner panel structure. Once separated, remove damaged quarter panel completely from vehicle. Inspect all mounting flanges on vehicle body for damage or distortion - straighten as needed with body hammer and dolly before proceeding.
10. 10

    Prepare mounting surfaces on body structure
    Grind away remaining spot weld material from all mounting flanges on inner body structure using angle grinder. Surface should be clean bare metal but not ground so thin as to weaken structure. Clean all seam sealer and adhesive residue from bonding surfaces using wire wheel or scraper. Verify all mounting flanges are straight and undamaged. Apply weld-through primer to all bare metal surfaces where new panel will be welded - this prevents corrosion in weld joints.
11. 11

    Test fit and align replacement quarter panel
    Position replacement quarter panel onto vehicle and secure temporarily with panel clamps at multiple locations. Verify door gap is even and consistent with pre-disassembly measurements (confirm target gap against OEM specification — do not assume a generic value). Check wheel arch opening alignment with opposite side. Verify trunk opening alignment and that weatherstrip surface is flush. Check fuel door opening alignment. Measure diagonal dimensions recorded in step 6 and adjust panel position until within 2mm of original measurements. This may require multiple clamp adjustments.
12. 12

    Clamp and secure quarter panel for welding
    Once alignment is verified, install panel clamps at all critical alignment points: top of wheel arch, door shut face edge, trunk opening flange, and rocker panel flange. Use minimum 6 clamps to maintain position during welding. Verify all mounting flanges are in full contact with inner structure. Double-check all gap measurements one final time before welding begins. Have assistant verify panel position from multiple angles.
13. 13

    Weld quarter panel to body structure
    Do NOT weld the composite quarter panel. Bond the replacement panel using the OEM-specified structural panel adhesive along the factory bond lines and reinstall all mechanical fasteners to the spaceframe. Work from center outward and clamp until the adhesive cures per manufacturer specification. Verify all bond joints are fully seated and all fasteners are torqued to OEM specification. heat distortion. Complete all structural welds before moving to cosmetic areas. Total plug weld count should match original spot weld count from step 8.
14. 14

    Grind and finish weld areas
    Grind all plug welds flush with surrounding panel surface using angle grinder with 36-80 grit disc. Work carefully to avoid grinding through panel. Weld areas should be smooth and level with surrounding metal. Apply body filler as needed to any low spots or imperfections in weld areas. Sand filler smooth when cured. Apply seam sealer to all panel joints matching factory seam locations - this includes rocker panel seam, rear body panel joint, and wheel arch inner flange.
15. 15

    Apply corrosion protection and primer
    Spray corrosion protection coating into all enclosed cavities through existing body drain holes or access points - focus on rocker panel interior and quarter panel inner structure. Apply weld-through primer or epoxy primer to all bare metal areas including weld zones and any areas where coating was damaged during procedure. Allow proper cure time per product specifications before proceeding to paint preparation.

Reassembly

1. Reinstall fuel door assembly and verify smooth operation of release mechanism before final paint
2. After paint and final finish work, reinstall rear bumper cover ensuring all mounting tabs engage properly and panel gaps are even
3. Reinstall taillamp assembly, verifying gasket seals properly and all lights function correctly
4. Reinstall trunk interior trim panels and carpeting in reverse order of removal, ensuring all clips are fully seated
5. Reinstall wheel arch liner and verify all fasteners are secure and no wiring is pinched
6. Reinstall rear wheel and torque lug nuts to specification
7. Reconnect battery negative cable
8. Verify all lighting functions (taillight, side marker, license plate) operate correctly

Verification

• Verify all panel gaps match opposite side and are consistent (door-to-quarter, bumper-to-quarter, trunk opening)
• Check that fuel door opens and closes smoothly with consistent gap around perimeter
• Verify door opens and closes without interference and latches properly
• Inspect all weld areas for complete penetration and no visible gaps or separation
• Verify trunk weatherstrip seals properly along entire quarter panel flange
• Check that all lighting assemblies are sealed and functioning
• Confirm no welding damage occurred to wiring harnesses or fuel system components
• Road test vehicle and listen for any rattles or wind noise from quarter panel area
