Probably the lower hinge. I have been informed that the 91-93 hinges are not the same as the 94-96 hinges. You may be able to repair it. If you have to replace it, open the gate down, and let the cable/spring hold it while you are replacing the hinge. Place the replacement hinge as close to the original position on the gate, and tighten. Then put the nuts on the inside of the body loosely. Carefully close the gate until you have the upper hinge/latch latched on both sides, and then get someone (have them inside before closing the gate) to tighten the nuts from the inside, or crawl in on the bed. You do not have to worry about the linkage if you are only replacing the lower hinge/latch. If you have to replace the upper hinge/latch, you probably need the FSM to adjust the linkage.
