I looked at my WSM and the lever attachés to some fingers that are spring loaded and fit in the detentes in the rail. Your going to have to buy a long slender common screwdriver to lift the fingers up in order for the seat to slide on the rails. The fingers look like they are at the rear end part of the seat. This will be a tight fit for you as you will have to have your head pressed on the floor to see what you are doing. This is where the little guy comes in handy. Once you have the seat able to slide, remove the bolts at one end and slide the seat back to remove the other bolts. Upon reinstall you do not tighten the bolts all the way until the seat moves freely forward and back. You have to go back and forth until the bolts are fully tightened to make sure the seat moves freely. I wish I could be of more help.

Cheers,
