Pro Tip: If you have a nice interior in your fox body, you'll want to cover the seats and trim of the interior when you remove the headliner. There may be a significant amount of residue. It is also a good idea to clean up the roof while the old headliner is out *of the cabin.

Step 10: Cut New Fox Body Headliner Holes

Grab your new Fox Body headliner and a razor blade. The holes for the dome light and map light are already pre-cut. Find each of these holes and use the blade to cut an “x” shape from corner to corner.

This will allow you to fold back the headliner and insert the map and dome lights through the hole without seeing edges on the headliner. Repeat this process for the visor holes.

Step 11: Insert New Fox Body Headliner Panel

Feed the headliner into the cabin through the back hatch. Tuck the headliner into the plastic panels in the back. Next, secure the headliner to the roof by reinstalling the map light. Slide the light and molding through the pre-cut hole and tighten down the screws to install it.

Pro Tip: Make sure your hands are clean while you're installing the headliner so you don't leave fingerprints on the roof.

Step 12: Reinstall Coat Hanger and Dome Light

Insert the coat hanger and dome light through the pre-cut holes in the headliner and reinstall the screws to secure them.
