Thanks for your replies. I called Subaru in Bangor and they said that they use the vin number of the vehicle to determine which brakes are applicable.
What was funny was that NAPA still didn't show any difference in the pads, even though I brought in my original equipment pads in to show them the difference. They were able to find the correct rottors. I had to go to VIP for the pads.
While I had it in the garage we checked the front brakes and I'll need to replace them in a month or so. I hope I don't go through the same song and dance to get the correct parts with that project.
Thanks for your responses.
