The headliner is self explanatory. Take out dome lights, handles, trim along the edges, front pillars, trim piece on the back, and trim piece on the front. From there it drops down in the front, slides forward a little, and then take it out one of the back doors. You don't need to remove the upper trim pieces in the back or b pillar vertical piece. My car had some stupid aftermarket sunroof in it and didn't have a headliner when I got it. I ended up epoxying a 3000gt and 2g talon headliner together, covering it with sprayfoam, carving it into shape, then recovering it. I used contact cement from aubachon hardware brushed on. I even made my own vanity shade, and recovered the visors. No pics of it in yet.
