so i want to change the front end of my 98 range xlt to the version of a 01-08 version of the lights bumper and grill. I was wondering if I went out and bought the header panel if it would be able to be mounted onto my truck.if i can not mount the 01-08 version to my truck then i know ill have to remaster my front end. i do not know if the bolt patterns are the same or if anything. im asking will it fit perfectly along with the lights or if i have to buy new pigtailes and swap them all out for the 01-03 xlt version unless i cant keep the same pigtails and just swap out the headlights casing. same with the bumper id like to mount a 08 or 04 front bumper to my truck since its bent, dented, and the under guard is gone. will the mounting brackets be the same?
