THE NUT PORTION OF THE CLIP MUST BE POSITIONED TO CONTACT THE SEAT SUPPORT LEVER.

THE AMOUNT OF FREE MOTION PRESENT VARIES FROM SEAT TO SEAT. IF AFTER INSTALLING THE CLIPS THE SEAT BECOMES DIFFICULT TO LATCH, IT MAY BE NECESSARY TO REMOVE SOME OF THE MATERIAL AT THE NUT PORTION OF THE CLIP (FIGURE 3). FOR MOST SEATS A REDUCTION OF 4MM WILL BE SUFFICIENT.

IF THE LATCH MECHANISM WILL NOT WORK PROPERLY, THE SHIMS MAY BE REMOVED AND MORE MATERIAL TAKEN FROM THE SAME LOCATION (FIGURE 3). 7) INSTALL STORAGE CONTAINERS.
