It's been a while, but if I remember right you have to turn that sliding plate on the e-brake handle kind of sideways while the floorboard is part way up and slip the sliding plate through the floorboard, then the floorboard will come up and over. I don't remember if the part of the floorboard that the pedals go through has to be removed first, but i know that the two pieces have to be apart. Hope this helps.
