This 5.0 Resto kit has EVERYTHING you need to convert your 1987-93 Fox Body Mustang 5.0L to five lug the right way!

Fitment Note
From the factory, your car came with a 28 spline differential. Upgrading to a 31 spline differential is required for this kit!

1979-86 Mustangs and 1987-93 2.3L Mustangs need to use 1987-93 5.0L spindles, struts, and calipers for this kit to work.

Fitment Note
- Fits ALL Mustangs equipped with an 8.8 rear end.
- Although we have seen other wheels not listed above, modified to fit with this kit, we cannot guarantee correct fitment outside of this list.
- Some Mustangs may require front fender/fender-well modifications depending on tire size and ride height, especially 1987-90 because of the smaller wheel opening. 1991-93 Mustang has a larger fender opening but still may require modification. Modifications typically consist of trimming the fender and lower front spat for tire clearance, and/or trimming the wheel well liner.
