Why have your friend look for one?
XATracing has PLENTY of them for sale and you can get an sr package meaning you can get the car and an sr swap all in one. I'm not trying to promote one shop over another but if you seriously want a 240 and you seriously want a swapped 240, I know that they sell them and do quality work. It would more than likely be cheaper than finding a car and THEN getting a swap done.
