There are four bolts holding the seat pedestal to the floor. Stick your head over the left front tire and see if you can locate these bolts. See if there is room to move the seat the 2 inches needed and still have the bolts in something solid. If so, remove the bolts and move the drivers seat out of your way. Lay out the four new holes and drill. Drilling holes through carpet is not easy. The carpet fibers will grab the bit, start twisting with the bit and will ruin the carpet five feet or more from where you are drilling!! METHOD A: Use a short piece of rigid, metal electrical conduit. 1/2" for this job I think. 10" or greater in length. Good square cut on one end. Heat the end of conduit with a small propane torch. Use the hot end and push while twisting to melt a hole through the carpet. This fuses the fibers much like melting the end of a ski rope to prevent unraveling. You can now drill through the floor without twisting carpet fibers. WARNING: Be prepared for fire! Have water available. Use gloves. METHOD B: Use a hole punch. The kind used to make gaskets. Or make your own punch by sharpening the end of the same piece of conduit used in method A. This method still leaves the possibilty of carpet fibers grabbing the bit. Be careful!!!
