6 With the foam securely in place, the new Sport Seat cover can follow. The covers are lined up along the front edge and more hog rings are used to hold it down along the insert. Since the foam has a wire structure in it, these hog rings are much easier to install. With the stock foam you would have to push the hog ring through the foam and try to grab the wire below. In that situation you are working blind so the new wire configuration is a welcome addition.
