Has anyone found an aftermarket rear caliper bracket that is the police version (also called the larger bracket, or bracket adapter)? I just bought a complete set of new slotted and drilled rotors and the rear rotors are 13.75" dia. My 2006 RT stock rotors are smaller (about 12 5/8" dia) so the brackets are too short. I've searched everywhere and can only find the mopar version for $80 each. Seems a bit excessive. Anyone have any ideas?
