ya, plastic parts.. i busted off both of my rear mudflaps/fender flares on a rocky run over the weekend, just leave a couple little holes in the plastic rear bumper, barely noticable, going to pop the front flare crap off the front bumper to match it up. as for the front flaps they continue to pop out of place and such so i plan to trim the bottom off so this stop happening because it seems possible that this might eventually cause some damage to the front fenders.. to be honest it looks better without the mudflaps anyway!
