It took me about two hours to get to that point in the image without knowing anything about removing the headliner. I think I broke maybe three fasteners along the way. I don't really know how I would have stopped that unless there's some specialized tool that I don't have/know about. Plus, they broke at the plastic where it clips into the metal fasteners. Not really sure what to do about that one. I guess I'll put it all back together and see what happens.
To get to this point I removed: sun visors (with electrical connection), front ceiling light, 4 grab handles, rear ceiling light, rear seatbelt mounts, rear speakers, and then the immediate plastic and metal (!!!) trim surrounding the roofline. I left the D-pillar trim in place and just finagled the headliner out from there. I only pulled back the A-pillar trim enough to do the same at the front.
No plans for holes in the roof. When it's time for rearward facing lights I think I'm going to tie it all in to the rear bumper and the tire carrier. There's already some wiring that's run back there for the CB antenna, so I might as well just follow along with that.
Anyone have any preferred material to re-cover it with? Or is standard, foam backed material sufficient?
