Not sure about the
Snugride in the center -- if you can get a tech to help you get it in without the base it should work ... but I suggest not taking it out untill baby outgrows it, then

The RA should work
RF between the 2
FF MAs, but it's not exactly easy

Check your vehicle manual because Ford will likely allow you to install it with
LATCH (as per
Britax approval), which I found easier to maintain proper install than with seatbelt: otherwise the seat slowly sunk into the 60/40 split. Then install the outboard seats with seatbelt.
