Dlyttle managed to track down a retailer who spoke with the home office and got us some dimensions and weight.
Susan over at the Pack and Ship in Aukland (thanks for the tip artig) gave me some quotes to let me know how bad the shipping could be (pretty bad) and authorized my having it shipped to them once she knew I wasn't going to freak out when I got the final quote.
John over at Fully Equipped in Christchurch (thanks for the contact Dlyttle) helped by taking my money and putting metal in a box for us.
Along the way we discovered one of life's mysteries which is that the 420 part is cheaper by more than $200 (US and NZD) if purchased in UK. I happen to have spoken with a place that had it in stock earlier this week. So, even if the shipping is expensive for that heavier part I should still come out ahead, so I'll call them when they open in the morning.
Then.... I get to order the cross-bars from someone in the US.
This is the most complicated, and multinational, order we've ever made, and it wouldn't have been possible without the help of you fine folks.
Thank you all for your help and suggestions. We really appreciate it.
P.S. our 32 year old Frankenstein vehicle has the last OEM windshield washer pump in the US (possibly anywhere) and now she's about to have one of the last few crazy-tall roof-rack adapters in the world... I don't know what that means but it makes me smile.
Her name is Sally, and this is what she looked like before we got started bolting things on and ripping things out.

I don't know what those Land Rover folks are thinking. No challenge.
