I would like to replace the vinyl cover on the center armrest. I have gotten the cover apart so I can get to the fabric but to put the new fabric in and secure it to the top cover, it would appear that the bottom part, which is the hinged part attached to the folding armrest, should be taken off so that proper pressure can be applied to get the two pieces of the plastic cover properly aligned and snapped back together. Any screws or bolts holding the hinge on the seat are not visible. Does anyone know how to access them? Is it necessary to remove the hinged part of the cover to get the two pieces properly aligned? Any help or suggestions would be clearly appreciated!
