Hey I was wondering if anybody might know a part number for the Mach 1 Caliper brackets for the larger cobra rear brakes... I already put the rear end In the car and for now just put the GT brackets and rotors on the car it get it rolling.... At my dealership the parts guys are not having any luck getting me the right bracket so i was hoping someone might just have the right part number to make it easyer for them thanks for any input..............
