I tried that method and after loosening all the bolts the bumper cover WOULD NOT move. You could lift the rear end of the car up seveal inch's and it would not move! We were putting so much pressure on the cover it was about to break. Mine is a 00 SVT so I dont know if something is changed but every bolt in that FAQ was completely loose however the cover acted like it was welded to the car. I sure would like to fix this, but I dont know what else to do.
