Cut the top section completely off. Take a section out of the remaining floor to get the drop you need. Split the top section down the middle and lay it on top with the corners and sides lined up and tack the top section back on. You will have to add a small strip down the middle of the top section and one across the back. You can add some thicker plate strips under the floor to make it stiffer and more support for the bolts.
