First off, Welcome to the site! Im assuming you want to do this to clear some version of a frame notch? Have you purchased a truck that has a step/notch done to the frame & they didn't finish the bedfloor? If not then not to be a downer, but more of a realist...Raising the bedfloor on one these trucks is a very simple project due to the mostly bolt together design & requires only basic knowledge/skills & eqipment. What I'm getting at is: "If you don't have the knowledge or the ability to do the floor...you have MUCH more important/higher skilled projects that you need to find someone to do & whomever you get to do that, will surely be able to do the floor" Just My Thoughts, Lorne
