There are plenty of guides around, just have a search on google.
You need: wings, headlights, bumper, grill, bonnet from a facelift.
Where the bumper attaches near the slam panel, (the two holes either side of the grill) you need to cut a small section of metal on either side. Its quite obvious where you need to do this when you line up the bumper. Then drill 2 new holes to put those plastic pin thingys in. Everything else just bolts on.
