Just finished mine, took about 3 hours.
Tools needed:
T50 Torx bit and ratchet
Philips screw driver
Needle nose pliers
X-acto knife
(3) Rear headliner clips )
1. Pull all trim loose from around the headliner. Start on the passenger side working your way around. The A-pillar will have to come first.
2. To remove the metal trim above the doors, you have to stand outside of the car. The metal trim is held on by three clips per side. The clips have an inside tab and an outside tab. To remove the metal trim from these clips, grasp the trim with palms up and pull it toward your body at a downward angle. The metal piece will pop off the outside tabs and it will hang down a bit. Then, push the piece toward the inside of the car to pop the metal trim off the inside tabs. Don't break the clips because they are not easy to find anywhere. Remove the three clips on each side with a philips screwdriver.
3.*** Remove the seatbelt mount by popping off the cover and using a T50 Torx bit.
4.*** Remove the B-pillar window trim and door trim.
5.*** To remove the metal trim from above the rear window, you will need two flat blade screwdrivers. You can try pliers, but two screwdrivers are easiest. Remove the two Philips screws, one on either end of the molding. Pry the metal trim down a bit until you can see the three plastic clips. They have a triangular plastic piece that inserts into a slot in the roof. Use two flat blade screwdrivers and squeeze the bottoms of the triangle together while having a partner pull down on the trim. It should either pop out or the clip will break.
6.*** Unbolt the sunvisors.
7.*** Pop the cover on the interior light in the center of the headliner. Use needle nose pliers to remove the two fasteners on the studs and drop the dome light down. Let the light hang by the wires for now.
8.*** The board needs to be removed. I didn't care much because mine was going in the trash, but you can easily ruin your factory board by not being careful.
9.*** Leave the front metal trim along the windshield IN the car. This one is a bear to get out and you are better off not messing with it in my opinion. You can slide the headliner back and down to get if out of this trim piece.
10.* Now, it is time to remove the headliner from the car.
11.* Slide your seats all the way back, and recline them as far as you can.
12.* Tilt your wheel all the way up.
13.* Have both doors open and see if you can get a friend to help you maneuver the board out of the car. You must take it out the passenger side, it won't clear the wheel on the driver side.
14.* Drop the front of the board down a little and rotate the front so it comes out first. You will want the passenger side up against the roof and the driver side against the floor.
15.* Make sure the board goes over the shifter not under it or it will bind.
16.* Play with it a little and it should come right out.
17.* Now that the headliner is out, the interior is pretty bare up top.
18.* When this is all done you can reverse your process and reinstall the headliner. You may have to cut holes for your dome light and sun visors. I cut my dome light hole with an Exacto knife while it was out of the car. Don't try to cut the sun visor holes out of the car. Just wait until you have the headliner installed and this will be your last step.
19.* Roll your headliner a bit to get it into the passenger side of the car. It is fine to roll an ABS liner since it is tough and will return to shape. Do NOT attempt if you are re-using your styrofoam one. Use masking tape to tape the wire to the dome light so you can easily locate it to pull it back through.
20.* Slide the headliner into the metal trim above the windshield. It is helpful to have a friend, but I used my head to hold it up.
21.* Attach the three plastic tabs to the passenger side and driver side to hold the headliner up. Remember, these were the tabs that were above the metal trim in step 2.
22.* Pull the dome light through and let it hang.
23.* Install the A-pillar moldings and the B-pillar window trim.
24.* Snap the metal trim in place above the doors ... you know, the ones you swore at in step 2.
25.* Install the metal trim above the rear window. Position the triangular clips in the metal molding first and then position it in place so the clips line up with the slots in the roof. Pop them in place with a few pounds of the fist. Insert the two screws, one in either end of the trim.
26.* Push the headliner up by the dome light hole to reveal the mounting studs. Mount the dome light and secure it with the little metal rings you removed in step 7.
27.* You are almost there. It is now time to mount your standard sun visors. Use your finger to locate the hole in the roof. It will be easy to find. Trim the hole out with an Exacto knife.
28.* Use your finger to find the three screw holes in the metal roof. Use a sharp punch to poke a hole through the headliner for the screws.
29.* Mount the sun visors.
