All I can say for the old ZD1's is good luck finding 'em in New Zealand! I can't find some anywhere here in Canada or the states! Some Ford dealers, and even IH dealers have told me they can still be ordered, special order that is, at the tune of 31$ a piece.....

Some other places don't even show the part number for 'em anymore, some places say theres a new part number, and some places say they have been discontinued and can't be had anymore.
