What exactly do you mean by 'Front end?' In order to convert to the newer bodystyle look of the 2004, you need to change the hood, both front fenders, complete bumper, grill, headlights, foglights etc. If you have all the parts, YES it can be done. THere are also some minor modifications that need to be done such as the wiring for the lights. The new headlights are bi-xenons with different connectors which will require fabricating a new harness. There should be a post in the article section by someone who has done this facelift...
