Hi Mark,
I passed your post to a buddy of mine that has a very nice 70 SII 2+2. It's a factory A/C car . It's had an extensive amount of high end restoration work done to it years ago. Very nice car. He's mentioned selling it but never moved on it. I just got off the phone with him and he's open to chatting. You might get lucky and hit him at the right time. Good luck!
