If you rub on back side of lining then you should pull the one screw from bottom of shroud out,then you can pull it forward revealing a joint that's glued together. I had to cut a half inch off so that i could heat up the plastic and gain clearance. But my concern would be damaging the tire depending on how bad you rub. I also tried heating front driver side i pretty much have perfect, passenger side i took out the grate for my oil cooler ground it down and pushed it forward. I still currently rub on passenger front but I'm either going to make a flat cover from louvered metal orv try shave down front and mold plastic more as ib only need quarter inch
