Many people view a Mustang as a me-too car since they’re so popular. However, one of the reasons they are so popular is the limitless number of modifications available to them. Plus, styling and performance options can be taken from one model and applied to any other Mustang of the same vintage. One such example of this crossover is the ’03-’04 Mach 1 and its front-end treatment.

The 2003 Mach 1 not only had a robust Four-Valve engine, but also a GT-style front bumper cover with a front spoiler and a floating horse in the grille opening. GTs have a grille with a running horse encased in it. The Mach 1 did away with the grille. Think of it like the 1993 Cobra grille versus other Fox grilles. Treating a New Edge GT or Bullitt to a Mach 1 front-end is much the same.

This is what a Bullitt looks like after installing the AmericanMuscle.com Mach 1 appearance package, and tinting the headlights and foglights. If you remember, the ‘01 Bullitts didn’t have foglights from the factory, so you’ll have to pick up a foglight switch, which installs in the factory location under the stereo. My Bullitt was pre-wired for the foglights, both at the bumper cover and for the switch under the radio. You may note the small holes at the front of my Bullitt’s hood. No one hates hoodpins more than I do, and my Bullitt had them when I purchased it. I haven’t found a quick solution, but I also couldn’t stand them so I simply removed them for now.
Now you can compare the before and after shots. The headlights in this image are genuine Ford items and replaced the funky headlights the car had when I bought it. However, tinted headlights were in order for the Mach 1 conversion. The Mach 1 grille-delete replaces the grille with a type of floating running-horse arrangement. Frankly, after seeing the Mach 1 front spoiler on my car, I don’t know why anyone with a GT or Bullitt wouldn’t have one on their car.

When I purchased my 2001 Bullitt, I quickly realized I am not a fan of the GT grille, and I wanted to make some other changes to the front of my car, as well. I made a call to AmericanMuscle.com for a Mach 1 appearance package, plus some tinted headlights and foglights. Since I have a black Bullitt, the tinted headlights and foglights lend a menacing look to the car, and with only 248 hp at the feet, my Bullitt needs all the attitude it can get.

Follow the photos and learn how to upgrade the front of your New Edge GT or Bullitt.

The factory GT and Bullitt grille is held in place with four push-plugs on top and four screws across the bottom. Remove the push-plugs and screws, and remove the grille.
The lower lip of the grille-delete hooks onto the front bumper cover at the back, and uses push-plugs on each side to hold it in place. The Ford running horse screws in place into the stock grille frame.
Here’s a look at the AmericanMuscle Mach 1 front spoiler. The spoiler arrives in a box much smaller than you expect, and AmericanMuscle recommends leaving it in the sun to be sure it returns to it’s natural shape before you install it. In the Sunshine State, this part is easy.
The front spoiler and foglights went on with the front bumper on the car. If you have the time to remove the bumper and install the pieces, especially the foglights, it will be much easier. I duct-taped it in place and drilled the holes needed to mount it once I knew it was in the right spot. Tape the sides flush to the bumper cover and make sure both sides are uniform. Don’t be intimidated by this operation. Measure twice, drill once. Once you have the holes drilled, use the provided hardware to permanently attach the spoiler.
Finally, AmericanMuscle has a myriad of headlight choices for New Edge cars; for me, tinted was the only way to go. Plus, I could get the foglights to match, which is exactly what I did. Note that the foglights install in the factory location, but you have to come up with your own mounting hardware. Patience is the name of the game. The bumper cover is drilled for the foglights, so just pick the correct side and use your hardware to install them. Plug in the harness for each of them, and you’re in business.
With the new headlights in place, you’ll have to adjust them accordingly. The best way to do this at home is to aim the car at a wall, turn on the lights, and use the adjustment screw to set them in the right spot. Night vision isn’t as good as with the stock lamps, but it is still adequate for night driving.
The headlights are by far the easiest part of this operation. By pulling out these clips, and detaching the headlight and parking light harnesses for each light, the headlights almost fall out of the car.
With the lights installed, the last thing to do is install the foglight switch. In this case, the local Ford dealer was the source and installed it in the proper place under the radio. The wiring is all there, so it was a simple plug-and-play operation for the switch. It just took a minute to fish the harness into place, but now it is in there and everything works as it should.
