I got a box from FCP a few days ago with new left and right Rear Trunk lid Lights (63218383183/4) and new trunk lid "Stoppers" (51247004475/6). Rather than let the box lay around the dining room for a few weeks like I usually do, I took a break from painting my newly rebuilt shed and installed the new pieces.
My trunk lid had been making creaking and other noises for a long time when the body flexed over bumps, etc. and I'd previously replaced the long worn out "stoppers" that go on the car itself. Those new and improved pieces have a spring action to them that works great and keeps from having to slam the trunk lid so hard, but the noise persisted. The Stoppers that I put on today are the pieces that bolt onto the trunk lid and to which the gas strut attaches to. They have a rubber perch that mates to chassis mounted stoppers when the cars is closed up. Super easy install and quite satisfying in that the noise is completely gone. They took a while to get, but they were not too expensive via FCP.

The lights were also easy to do and look 100% better than the old hazy and cracked pieces. One lens came off completely while taking it off and it was filthy under them and needed a good clean after removing the OE pieces.
