Headliner removal, where the clips are

We recently had some postings on this. Found a japanese site with a lot of pics, which might be helpfull. It shows the clip points in A/B/C pillars, whre the headliner is held in the roof, where the wire connectors are for the interior lights, there the screws are for the sunroof etc, and finally some pics about the headliner replacement.
Hope that helps

Edit: just noted that sometimes the link does not work, as it goes back to the E34 main page in Japan. On the right side click E34 M 5 , there are a lot of tips.
The direct link to the headliner replacement is here
