dont do the cobra r front spliter, it looks bad and you are just asking to destroy it as its to low to the ground.
Go with ford racing it should cost about 375.00~ with foglights and bezels and chin spoiler (or should be around that might be more)
Then all you need is the fog light wiring harness if you dont already have fogs, and the connectors for 03/04 fog lights are different.
The issue with your hood is it will fit but it will be very close to the hood, the 03/04 cobra bumper posts come up higher so it WILL rub your hood. Most pull the posts back more~ or something and its ok. Just FYI.
You an go with the hood as well, check ebay for used parts... you will have it painted anyway
just buy a brand new chin spoiler as 90% of them are hosed up lol (125.00 each new it seems...)
part price break down from what I know
Chin Spoiler 125
Bezels 15 each
Fog Lights 140 a set
has probably the BEST prices so call them and get it all priced~
