I scored a 6V Delta CDI not too long ago.  It was sold to me as working, but you know how those things go ;)

Haven't had the courage/motivation to install and test it yet, though.  It's tough when your car runs perfectly well already -- I just wanted it for prolonging point/plug life.  I forget, where do you prefer to install CDIs?
