Has anyone adapted 98-02 f-body front brakes to a chevelle? If so what is required?

the rears bolt right on, you may need to space the backing plate out some to get the caliper lined up with the rotor. The fronts just need an adapter bracket to bolt to the stock spindles. You can get them from Joe http://www.engineeredvelocity.com/ turn down the drum hub so that a vette rotor fits over it. Joe can help get you set up.
