No, you need to recover the headliner. When you remove your pillars, the headliner will come down. Get some 3M general adheisive spray for headliners, and get some headliner material. Call your local auto trim and interior shops, they sell headliner material in all kinds of colors. Just remove the headliner, spray half of it with the 3M spray, being careful to follow the instructions on the can, and also spray down half of the new headliner material, lay it down, do the other half, then trim off the excess. Leave just a little on the front and rear of the headliner, so you can wrap it around.
