Unfortunately the history data on that site is not entirely accurate, at least not for the US. Point in case (pardon the pun) the 240Z did not recieve a transistorized breakerless ignition. This did not happen until the release of the 260Z in 74 as far as I am aware. Mine certainly didn't come with it.

Seems to me that's the same text (errors and all) from the "History" printed in the front of every Black Dragon catalog.

Also in age. Which does mean something.

If you have a green beard and like pink flloyd, these things do not concern you.
