On a 300tdi
If its the front pillars by the windscreen then there are 3 clips which give way when you pull them, its better with a long screwdriver for leverage, take car as they break easy.
For the seatbelt mountings then leave them in place. Front sunvisors have to come out, then the front map reading panel. This is held in with lots of screws and the light, sunroof leckies and ultrasonic sensors are held in with multiplugs which you need to pull apart.
All grab handles need to come out and also the rear alpine light surrounds, the seatbelt bolt is 17mm.
If you do it this way then the headlining will be held up via the interior mirror, seatbelt mountings and the lip at the rear of the tailgate.
Just lift up and flex and out rememberingto disconect the rear interior light, oh yeah, put the rear seats down when removing as it helps :oops: :lol:
If you break the rear interior light, they are hard to source but if you go on Ebay, the interior light from a Rover 800 is the same
