Currently installing new Legendary seat covers. One of Their installation kits comes with 3/4" hog rings and pliers. You need hog rings as opposed to zip ties etc, because it can be VERY hard to get that new vinyl stretched over new foam. You need 1 hand to pull/stretch and the other with the pliers. These are what came in the kit. Turns out they are made near where I live in Ontario, Canada!! I needed some more, and ordered them.
