www.car-part.com You'll actually be looking for SVT front bumper (cover) SVT rear bumper (cover) & rocker moldings...A junkyard will be confused if you ask for a "kit"...so would Ford, it's not a kit, unless you might find a complete set from someone selling theirs here. Side skirts (rocker moldings) are more difficult to find & you might be better off buying new.
