After the seatbacks and cushions have been separated, flip the cushion piece over so that the of the cushion is facing you. There are four (4) bolts that hold the frame rails to the seat bottom (see Figure #4). Unbolt and remove the seat frame rails from the seat. With the frame rails removed, you now have access to the hog-rings that hold the upholstery to the seat bucket. There are about fifteen (15) hog-rings around the perimeter of the seat cushion pan that hold the edge of the factory cloth/leather to the seat cushion pan (see Figure #5). Remove these with a pair of tin snips or metal cutters.
Now lift the edges of the factory cloth or leather cover up around the edges of the seat and towards the center of the seat, revealing the insert seam lines. The inserts use about eighteen (18) hog-rings to attach the covers to the foam core. Snip them and remove the cover (see Figure #6). The installation of the Leatherseats.com covers is the reverse of removal. Start with the horizontal hog-ring point that is across the insert, and then move to the edges. After you have recovered the foam core and seat pan, it is a good idea to go ahead and bolt the seat rails back in place before setting the cushion aside and starting on the backrest.
