Carpet material to replace sun-beaten rear shelf lining. Remove the rear book shelf and tear off the old carpet. Normally comes off with a minimal effort. You will need to have spray adhesive to attach the replacement. Work around the air vent area to shave off some of the thickness of the replacement material as it is thicker than the original and may need a little workaround. Trim extra material about 1/4 inch on the long sides of the shelf to have extra to work with while fitting the shelf is . Small metal brushes work nicely when thinning out the edges.
