I got a new one for $650. Also the flanges have been machined flat and it is ceramic coated. I am on MSF and my usernam is spd6tuner. PM me on there because I am not on here often.
email the guys on trucks (horsepower TV). They had a chemical bath that removes rust without damaging the actual part itself. Or go on powerblocktv.com and see if you can find it somewhere.
