I suspect the primary purpose of this shroud is to reduce NOISE...  not just
for appearance sake.

Maybe its so simple folk don't get too overwhelmed when popping the hood.

Thank you ford for covering everything except the windshield wash
reservoir and the fuse panel.

 Don't be too sure - they do not spend money on engineering, making,
and installing stuff like that without a /really/ good reason.

 It's probably there as added noise damping, and/or to channel
cooling air across the top of the engine because they were cooking the
plastic intake manifold, or something equally as stupid.

 If the dealer fasteners are too expensive, design an alternative.
Good hardware stores have various sized bolts with plastic handwheel
knobs molded on top - three of those with the appropriate Speednut on
the mounting bracket, and it's neatly (and cheaply) fastened down.  

 Take the one bolt you have left into an Ace or True Value, or a good
auto parts with a Dorman or Motormite bolt bin, and see if they can
match them.
