hi, can anyone help? i've recently purchased a 1996 e200 w124 that has the seven seats fitted. one of the seat belts for the rearmost seats is not fitted to its top (roof) mounting point. the bracket is on the seat belt but the bolt or stud that fixes it to the roof is missing. my question is can anybody tell me what type of fitting is used and can it be done at home or does it have to go to a specialist? thanks in advance for any answers, rod.
