Ford Lincoln LS 2004 Owner's Manual page 199

recommends that the child seat can be installed to anchors that are
spaced up to 500 mm (20 in) apart.
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 recessed at the rear
section of the rear seat between the cushion and seat back. The inboard
LATCH anchors are located below and behind the locator symbols on the
seat back. The outboard LATCH anchors are 11 inches (280 mm)
outboard of the locator symbols.
