To do a full GT front bumper swap you have first to choose a stock GT bumper or an aftermarket front Mustang bumper. The aftermarket options are all built to replace the GT bumpers. Once you have chosen the bumper then you can choose the GT lower and upper grilles you want to install with it.
There are a myriad of options. Chrome, Satin, or Black colors are available. Or you could order one pre-painted. They also come in plastic or metal construction. Some add lights and some delete lights. The grilles are a big part of customizing your Mustang.
The GT bumper for these years just bolts onto your V6 mustang frame with out hassle or modification. This would also be a good time to change out your front headlights. You can reuse your front orange side markers, but any fog lights most likely will not transfer. However if your new bumper has fog lights then you can most likely just upgrade the wiring harness to make them work with new lights.
The whole procedure only takes about 1 hour and you can use hand tools. In short you first pull the pins and remove the top radiator cover and then the lower under cover. Then remove two screws from each side of the wheel well. After than there are two bolts and two tabs on the top that lift up and pop off and then on each side there are tabs your pull out on and then you can remove the bumper. One person can do it but having a second set of hands comes in very handy. The last thing you want to do is scratch the paint on your new bumper.
Once you’ve completed this simple swap you are then free to style your V6 with any of the available GT grille options .
