Just FYI to our group. i think the reply was a scam..........doesn't make sense that someone would have "a few sets" when all of us have been struggling to find them for several years now. Also, it says he just became a member as of a few days before his post......just didn't smell right to me. I did send a reply to his email, but no response.
Still looking, but the performance shop I use (STM in Rochester, NY) suggested I contact cquence brakes out of Walnut, California. I did contact them and they suggested they can rebuild my calipers.
I will be sending them out to rebuild and I'll let everyone know if they can get it done. Fingers crossed
