I found my 13-14 OEM clutch on ebay from a dealer for a around $300 (I think). I shopped around and that was the best price I could find.
Because I'm not tremendously pleased w/ the DYAD, I put together this parts list the other day so that I can go back to my stock '14 clutch at some point. Considering Ford may obsolete these parts in the not too distant future, it will be good to have them on hand anyway. I would assume they would this would be all you need to bolt up to an 12 and earlier car. But someone can correct me if I'm wrong.
