I shortened mine....
Haven't been to active lately but all i did was removed the core support and attached the bumper cover to the bumper filler with rivets and trimmed back the excess, really wasn't hard. I used the center three bumper filler bolts to attach the bumper and two bolts on the corners. So far I haven't gotten around to mounting the fog lights, but that's due a IC pipe rebuild needed first. Looks pretty good. Shortened it about 2-3 inches.
