On my 2000 C4 I was lucky enough to have nylon screws. They broke of course, but drilling and tapping was easy with a few tricks and observations: Using a soldiering iron to melt a hole through the center of the nylon screw makes drilling MUCH easier Used a 3/16" drill bit to remove the majority of the nylon then used a 6mm x 1.0 to clean the threads Plunge depth is 3/4" Use a "bottom" tap rather than a "tapered" tap so you clean threads quickly and without significant insertion.
BigDam99 posted a topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Looking for a little help addressing a rattle in the headliner. It goes away when I press lightly on the horizontal bar that is located about 5 inches behind the sunroof. It doesn't appear to me the bar is disengaged, just rattling on a metal contact point. Can this be fixed by "reaching in" or must the headliner come down. If if the latter, does anyone know of a nice procedure that has been published? thanks in advance.
