In 1979 through 1990 the front Fox Body Mustang fenders were all manufactured in the same shape and design. However, in 1991, to accommodate the newly introduced 16-inch factory wheel and tire specifications, the front fenders on the 1991-1993 Mustangs were revised to feature a slightly enlarged wheel well opening.



1979-1990 Fox Body Front Fender

The 79-90 Mustang front fender, as shown below, maintained the standard design and curvature of the wheel well opening. All 1979-1993 front fenders are interchangeable, but they are year-specific if you want to stay period-correct or replace the factory fender. The wheel well opening for the 79-90 fender measures in at approximately 29 3/4". Check out our 79-90 front fender kit and our individual driver and passenger side fenders!

1991-1993 Fox Body Front Fender

The 91-93 front fender can be seen in the image below featuring the slightly larger wheel well opening that has a suttle slant shape to it. The slanted inner well opening is a sure sign to differentiate the later model fender. While the fenders themselves are interchangeable throughout the 79-93 years, be mindful of the fender extensions or fender spats as they will need to correspond to the year of the fender they will be going on. The wheel well opening for the 91-93 fender measures in at approximately 30 1/4". Here at LMR, we also offer a 91-93 front fender kit and individual driver and passenger side fenders!

FAQs

  • Will the 1991-1993 front fenders fit my 1979-1990 Mustang? Yes, the front fenders themselves are interchangeable throughout the 79-93 year models. But the corresponding fender extions, spats, and moldings will be specific to the fender.
  • Are the inner fender splash shields the same on both fenders? Yes, the inner splash shields across 79-93 fenders are the same. Check out our 1979-1993 Mustang splash shield kit for a quality replacement set!
  • Will the fender extensions cross over to either year model fender? No, the fender spats and extensions are year-specific and will need to match the year of the fender on which they will be installed.
  • Does the antenna need to be changed when swapping out fenders? No, the antenna base and cable mounting dimensions and locations are the same for all fenders 79-93.
