Ask I-CAR
Ford
Ford does not have a sectioning procedure for the front lower rail.
Per I-CAR curriculum: “If vehicle maker procedures or recommendations are not available, DO NOT SECTION.”
A tool that may be used to find out if the vehicle maker has a partial replacement or sectioning procedure is the I-CAR developed OEM Partial Part Replacement Search. https://rts.i-car.com/oem-partial-part-replacement-search.html
