The front end parts are pretty easy to deal with. Since you have no experience, you will likely have the most trouble with the wiring. You need to switch out the turn signal flasher to one from a mountaineer as well as cut off the wiring for the extra bulbs. The mounty only uses one turn signal bulb where the explorer uses two plus one extra small parking light bulb. The flasher looks similar to a relay and is located under the driver side dash near the OBD II port.
You would need:
Header Panel
Grille
LH & RH Headlamp housings
LH & RH Parking light housings
Mountaineer Turn Signal Flasher
This is what it looks like now. Before I had cut and painted over a factory chrome grille. Now I am running a factory painted blue grille from a salvage yard. The paint wasn't perfect on it but it is good enough for me right now and the color matches so I left it.
