Step 6: Now it’s time to re-install the mat. Here is where it becomes tricky. If you are NOT comfortable in pulling your seats, carpet, both left and right side panel completely out of the interior of the H3, I’d suggest you do the following. Use the carpenter’s knife to cut off the excess of the mat. It really serves no purpose other than noise reduction, but most of the excess contains little foam. You will do this because the re-install is impossible to complete unless you remove practically everything from the rear of the vehicle. This is the command decision I made.
Step 7: Not only did I cut down the side of the mat by 5-6 inches; I also cut the rubber flaps that were intended to fit tightly under the crease of the rear seats.
Very difficult fit, practically impossible without an entire rear seat extraction, a 3-4” cut was made. Still quite enough mat left to tuck away under the seat area..
Step 8: At this point, you’ll be over half way done; this is where you will need to get out the bottle opener:
Step 9: Pick a side, I chose the right, and begin tucking the mat under the interior panel. Continue to do this and use your weight and your body to force the mat into position. It will begin to resist, but insure your not forcing it and causing the interior panels to buckle.
Step: 10 While you are placing the mat sides behind the interior panels ensure you line up the anchor tether holes up. This will be one of the most important steps because you want to ensure the mat is not stretched or buckled before screwing in these anchors.
