Rotor Swap or Sell

I have three new GTS? (Brembo?) rear rotors (2x left and 1x right) which I would like to swap for PFC rotors for my GTRA. I need a LF and a RR). I'm uncertain they are GTS rears because they only have 8 bolt holes, not 10. They are 1.1 thick, have directional vanes and 8 straight slots per side. They measure 12 5/8 in diameter (slightly smaller than the PFC's on my GTRA. No markings. It might be possible they are some alternate brand for the GTRA/WC cars. Any ideas on what these are? I'm willing to swap even (3 for 2) or sell these rotors for $150 each. If I can't swap, I'll be looking to buy the ones I need. The rotors on my car are fine and will last at least another season, so I'm not in a big hurry, but I'd like to have the complete set of PFC's ready. I'm also looking for a set of PFC 097 pads and the hardware for mounting the rotors to the hats.
