to the OP. roll bar end links are anywhere from $) to 50 bucks. i suggest getting the moog units as they are greasable, and when maintained should last quite a long time.
i wouldnt worry too much about the radiator under tray. not may cars have them anymore.
however fender liners can be easily located.
a full replacement svt front bumper from ford i believe is around 500 bucks. and comes with the grilles and foglight brackets, and maybe the fog lamps too idk.
deffinitly take care of the brakes and tires. i suggest getting new pads and rotors all the way around, and perhaps stainless front lines.
part of an army of freaks. but you still love me.
