if you must have the name brand and the bear claw log on the calipers, then order a Baer track kit with 12" rotors.
but if you want the same parts for less than half the price- but without the logo on the calipers- then get Corvette or Camaro rotors, calipers, and mounting brackets and either make a bracket to mount it to your spindle or order one online.
either way, you are going to have to modify your spindle.
