How hard is it to remove the driver side power seat

Driver's seat raises and lowers, back goes forward and back, seat does not move. It looks like the seat has to be removed in order to access the motors and wiring. There are 3 bolts that are easy to remove, and the 4th, attached to the hump over the driveshaft, does not seem to have an accessible bolt. Is there a picture or a description of how I can remove this final bolt? I think your answer is correct, but if the seat can't be removed I don't see how to deal with the problem. Can you help with the driver's seat right rear bolt?
