Installing a show chrome driver back rest and need to know the trick to getting the rear seat pan lifted up to install the riser bracket that the backrest slips into. The slingmods video shows lifting or shaking the pan in the middle and instructions show lift up on right side. I can't get either methods to move the pan. Video says loosen bolts and instructions said remove the bolts, the bolts are completely loosened. Any help will be appeciated.
