Het all just a bit more for this topic , tortional twist was not just because of a sunroof as I have seen may examples of the -XE-XFs series Fords with serious body cracks with NO!! sunroofs installed its just one of the things that happened to cars back then , As for optional rattles any aftermarket sunroof was not designed to hold the weight of a DVD player to the bottom section a light fitting was okay but not a DVD player . When we install a sunroof if we know a DVD player is going to be fitted extra reinforcing can be fitted to strengthen the mounting area of the sunroof, we do this with VE calais that have factory fitted DVD,s .
