4. NOTES:
The graphic shown is of a 3 door, the 5 door rear wheelhouse front extension joints are the same.
Where applicable spot welds must be drilled from the inside, this will enable the new panel to be spot welded on installation.
Use a belt sander where there is no access to drill.
Drill out the spot welds.
5. Separate the joints and remove the old panel.
Installation
1. NOTE: Spot welds must be drilled from the outside.
Drill out spot welds on new rear wheelhouse outer as indicated.
2. Separate the joints and remove the new rear wheelhouse front extension.
3. Prepare the old and new panel joint surfaces.
4. NOTE: With panel in position check for access to spot weld the joints. Offer up the new panel and clamp into position. Check alignment, if correct, proceed to next step, if not, rectify and recheck before proceeding.
