The kit comes with new backing plates for the calipers. They bolt on using the stock mounting points, and are supported by moan brackets that bolt to the axle tube. The dust shields can then be installed along with the new, longer axle shafts. The axles are the same 28-spline units found in the '94-98 Mustang. Should your future include sidestepping the clutch with slicks, you may want to use a stronger axle, but for our application, these slightly thicker stock shafts will do fine.
