This is the 2nd phase of the 4th generation of Ford Mustangs. It should be called the 5th generation in my opinion because of the complete redesign. Because of the design of the hood, the 1999 – 2004 Mustang can handle 6″ stripes or 8″ stripes. For an even wider look pinstripes can be added to either kit. Anything wider than 8 inches will run wider than the hood scoop and make the installation difficult. GT hood cowl stripes are also perfect for this model. You can continue the GT cowl stripes back across the hood and rear deck by using 10″ striping. There are two hoods for this generation Mustang. One is the type below where the scoop points towards the windshield. The other is the more common one where the scoop points towards the front of the car. Both hold the same width stripes.
This car below has the scoop facing the front bumper.
The picture below is of 8″ stripes where they took a different color pinstripe and used it as trim. Looks good.
The car below was striped with an 8″ x 36 foot kit with 1/4″ pinstripes. All done by the owner.
