They do come up for sale on rare occasions. Mark will be able to tell you prices. Just google Mark Shead and his number comes up. Just bear in mind that you will need someone to map it to the car and they make a lot of torque low down so either get the mapper to be conservative for your running gear or get ready for a new box and diff if a 4x4. Mine was a low mile box and it didn't make 500 miles of low boost use.
