FORD 2002 Windstar v.1 - Manual (Page 173)

Never attach two LATCH child safety seats to the same anchor.
In a crash, one anchor may not be strong enough to hold two
child safety seat attachments and may break, causing serious injury or
death.
The lower anchors for child seat
installation are located at the rear
section of the rear seat between the
cushion and seat back.
Follow the child seat manufacturer’s instructions to properly install a
child seat with LATCH attachments. Two plastic LATCH guides can be
obtained at no charge from any Ford or Lincoln-Mercury dealer. They
snap onto the LATCH lower anchors in the seat to help attach a child
seat with rigid attachments. The guides hold the seat trim away to
expose the anchor and make it easier to attach some child seats.
Attach LATCH lower attachments of the child seat only to the
anchors shown.
