If you are talking a GM metric rotor, No Limit Engineering has a dual pattern rotor for that with 4 1/2, or 4 3/4 bolt pattern. They also have a 2" drop Mustang spindle that has the GM caliper bracket incorporated into it, and uses all GM metric parts, rotor, caliper, and hardware. Speedway has a large bore metric caliper that is the functional equivalent of the large GM caliper.
