Finally got the pics back and scanned for my black Microsuede headliner. Along with it I managed to track down the proper black sunvisors, vanity lights, map lights, grab handles, and a surprise.
With the light gray headliner falling down around my ears, I had to first strip the only one out and get it down to the bare glassfibre. After that came the foam. JoAnn's sells "headliner" fabric that is seriously ugly (unless you like bright red or blue) but has the thinnest foam they carry attached to it. I bought a couple of yards and stripped the red fabric from it before attaching the foam to the headliner base.
Here it is in black.. all done and ready to go into the car.
The C pillars were easy. Large, simply shaped, and no tight corners..
The B pillars were a pain. With their tight corners and the opening for the seatbelt slider, I had to get them exact.
Above the sunvisors, I have the black M3 vanity lights. Pretty hard to track down without spending a fortune. I also tinted the lenses with a light layer of black to make them less conspicious.
In the back, where the third light would be, I replaced it with a double lensed unit from an E34. I think it looks a LOT better.
