Ford does not have a specific procedure for replacing the passenger floor.

Structural Repairs for Ford Motor Company Vehicles: “Where no Ford supplied repair procedure is available, repairs must be made at factory joints or seams with Ford original replacement parts using procedures that duplicate factory assembly processes and techniques.”

Per I-CAR curriculum: “Replacement procedures for front floor pans are typically done at factory seams. Some vehicle makers may provide replacement floor pans, but no procedures. In this situation the insurer, vehicle owner, and repairer need to discuss the considerations to determine how the vehicle should be repaired.”
