The running boards came well packaged. It fit my 2021 Ford F-150 Super Cab (Extended Cab). My truck only had two sets of mounting studs so I only used two mounts. I don't think the third mount is necessary as these boards are quite heavy duty. Ford does provide holes without studs for a third mount so one could probably figure out a way to install the third mount; I just don't think it is needed.
