Is there a difference between the brake rotor used on a SRW D60 and a DRW D60? Advance auto lists the bendix rotor for SRW for 98.88 and the DRW for 82.96. They have different part numbers but I'm not sure what the difference would be. didn't look at them side by side cause they were special order. their cheaper rotors are reversed as far as prices go. thanks in advance.
