Paul,
Year One sell them from $825 for a black pad to $707 - $932 for other colours and speaker, A/C set ups.
Shipping to New Zealand via EXPRESS shipping is around $300 USD (2-5 days) plus any customs, which you may or may not get depending. Sometimes items sneak through without being hit with clearance $$$.
I'm calling the previous owner of my 'Cuda back in about 10-15 minutes as he said there is now a place in New Zealand called, "PG Classics" or something (what I am finding out) that restore these dash pads. I'll let you know ASAP.
I myself got a Year One pad for Lucy, looks really good but that depends on what one they send you. Some have really bad stitches in them, wavy and wonky and like mine some don't line up to the dash mouldings too well.
Cheers,
Carl
