Rebuilding a bench seat

If it's sagging that badly, you probably have one or more broken springs, look closely. Two were broken in mine. I have some bench seat springs, though different because of they are from a 4 door front seat, but they can be adapted. I also tied the springs together with ty-raps. Get a foam kit , hog ring pliers and rings from a farm supply store. Get your covers from a vendor, not Legendary. Legendary supplies the vendor, you will get it faster.
