When my kids were young I just ran the seatbelt through the car seat, they all are designed for latch or seatbelt. Yes its hard to get your hand through there but it only takes a minute or less, after a couple years they get into boosters that use the seatbelts anyway. I had Britax car seats and even in my escape which had the latch I liked the way the carseats fit using the seatbelt anyway. For our Britax's the latch points in my escape and her explorer were spread out to far and the seat would slide side to side. I also removed the headrests (of the Fords seats) as they held the carseats away from the back. My wife and I were always passing car seats back and forth and I did loose some skin off my knuckles a few times and we were doing 2 at a time. I trust the seatbelt that ford crash tests more than some latch strap made in some forign country! Just my opinion. Ford has a building that only crash test seats to test out the seat belts and they do use carseats and baby crash test dummies I have watched them do the tests, I work at the R&E center in Dearborn.
