UPDATE: In late 2020, Ford revised the F-150 outer box side replacement procedures to now include the use of self-piercing rivets (SPRs) in specified locations. This change only applies to the 2015-2020 F-150. Super Duty trucks will not be able to use SPRs for the repair procedure.

This change is due to a newly sourced SPR that makes the outer box side repair with SPRs possible. Ford has updated the procedure in the vehicle-specific Workshop manuals but not the instruction sheets. In addition to the SPRs, blind rivets or plug welds are still an option in the specified locations.
