there are 2 small clips that hold the upright back.. back must be removed.. you will need a long flat blade screwdriver to release the clips.... a small hand held mirror is handy to see clips 6 inches below the top of backseat.
there are videos online showing how.. this is not a 5 minute job... just tricky.
removed all of mine... no passengers ever. as there is no bottom of seat in truck as well
.unless Ford changed them again.
