I was wondering if anyone could help me. I have a Mondeo 2006 TDCI Ghia X. There is a black clip on the top of the rear seat where the seat belt disappears into the seat itself. It doesn't seem to fit my car. It is loose and keeps falling down. When I have tried to clip it back in place it makes the leather stretch which doesn't look right. Is there different clips for different models of car as I think this may have been replaced with the wrong part. I don't want to clip it in as it looks totally wrong and also when its hanging loose it doesn't even look like it will cover the hole in my seat which it sits over. The clip in question is for the centre seat belt.
