It was somewhat difficult to read the instructions (bad copy) and it seemed to be for a later model JK, but the seller assured me it is for a Wrangler TJ
The part arrived in a timely manner and was easy to install. There is an illustration that shows removing the tail light assembly to gain access to an existing fuel filler from behind, which is unneeded on the TJ type of vehicle. Additionally, the illustration stipulated that the six hex bolts on the outer trim ring were to be tightened using a torque wrench. As illustrated in the instructions, the hex bolts are only long enough for the trim ring to extend through, so they are only decorative and cannot be used to attach the ring to the body. It was the only way I could do it, and I broke the hinge in the process. After being approached by the customer service department at Hooke Road 4 x 4, I was immediately given a new one. My old fuel filler was removed just like before without any problem. I simply removed the four screws from the outer ring and removed the gas cap, which uncovered four more screws in the inner ring, before pulling the old part In the next step, I inserted the Hooke Road fuel filler door in the opening, aligned the four screw holes on the inner ring, and retained it by screwing it into place with the four screws. It took me about a minute to attach the lanyard of my old gas cap to its corresponding hole on the new part, install the gas cap, lock the fuel filler door and that's It took me just five minutes to complete the task! My hex bolts on the outer ring were not messed with In this case, the four screws on the inner ring are sufficient to keep it tightly in place.
