Could always go back to the stock size pad and rotor setup? Unless you can find a serial or some sort of brand stamp it will be difficult to determine where they came from.

I read on another forum from 2013 that the parts are from a 2013 GT500 but it also matches the casting number on 2011 and 2012 GTs so it looks like the part number you have is for a stock rear caliper for those years. Can you get us some clear pictures of the parts in question? Any part or casting numbers too.
