i am slowly picking-up the parts for upgrading the rear brakes to discs on a 93 mustang 8.8. i've got the backing plates, anti moan brackets, mounting brakets, rotors, i just need the calipers and axles and parking brake cables. i noted someone said the that gran marquis calipers would fit, but is there any other axle that will interchange with the 94-98 mustang axles as these are difficult to locate?
