Here are the pics from the sunroof. It's not working yet, but it seems that my uncle knows about these thing. He's like a walking service and repair manual. (He had a mk2 360 GLT when it was new ) So i better go and ask him for help

Nice...

Just got it al apart, took the roof upholstery off, checked the little motor, but the problem is inside de roof window itself. It'd probably be harder to fix then is thought

Nice example there. Looking at the headlining, it all appears to be different, to nicely fit the motor and different controls. It looks to be a well crafted job. All UK GLT headlinings were white or black/dark grey so it could be the flash, but it looks to be a light grey colour? Hope you get it working.
