Before any new parts can be installed, all the old stuff needs to come off. The best way to remove hog rings is to use a set of diagonal pliers. Grab the hog ring with the pliers and twist, which will un-bend the ring and remove it. The hardware, which holds the backrest to the cushion, is hidden beneath the back of the cushion cover. Remove the bolts with a 1/2-inch socket and keep track of the plate/tab because there is a left and a right for each seat, and they won’t work if they get swapped side to side. The plates serve two functions—to hold the metal trim and provide a place to hog ring the cover.
