Well my trunk/spare tire lid has been moved down to 6 ¼ inches. I tried pushing the truck floor up with a potra power, but it just falls down and does that oil can thing. I here chatter about shrinking sheet metal, but never done it. I was going to hold the floor up with some wood and then heat the floor some and see? Or I was going to lift the floor up and try pounding this small area at the apex of the sage back down and see. Need ideas
