Important: Some parts have structural weld-thru adhesive in the joint areas. It is necessary to replace this with additional spot welds at the attachment points. This can be accomplished by adding an additional weld between each factory weld in all areas.

Sedan floor pan with the addition of wagon reinforcements will produce the wagon floor pan assembly.

1. Note amount and location of spot welds.
2. Remove sealer and drill spot welds from:

•	Rear floor panel

•	Rear body panel

3. Add additional welds between each factory spot weld where reinforcements contact the rear floor and rails.
4. Clean all weld seams with a wire brush. Prime and seal all repair areas.
5. Apply permanent underbody sealant.

Important: Ensure that proper corrosion protection processes are used on all repair areas.

6. Prime with two-part catalyzed primer.
7. Apply sealers and corrosion protection materials according to information in the "Body Paint" section of this service manual or paint manufacturer's recommendations.
8. Clean surface for welding and grind primer off new part at connecting points. Apply 3M® Weld-Thru Coating P/N 05913 (or equivalent) to all areas to be welded.
9. Measure and align. Clamp in place.
10. Use MIG to plug weld.
