Accessories and Attachments

Hi,<br> According to the user manual ford double cabs have attachments available or compatible with baby seats and fixtures. From my experience no one of 4 ford dealerships I contacted including the main branch on Waltloo knows about such attachments. I was specifically looking for the iso fix base attachments for a baby seat. I have been told to use a pirate part or the seat belts. Why is this then included in the vehicles manual as compattible and available. This was one of the main reasons why I got the vehicle. I have sent emails explaining the problem and have not received any feedback regarding this problem....
