As far as I understand John Mate the Harrop Y62 ‘complete kit’ should be a relatively easy installation for a decent mechanic stateside there
I seem to possibly recall Harrop being our Aussie exclusive Patrol/Landcruiser distributors for your Eaton chargers with design added Down Under adaptions etc....?
A few of us are still playing around with your old dinosaur 6.5 Hummer military / Suburban type donks/engines and believe they were USA born Eaton screws for their kits too
Maybe worth sending Harrop an email to see if they’d be happy selling you all the extra/lighter postal bits and score the Eaton 2300 screws over there at home?
An ‘NDA’ could be required signed for private export use but really shouldn’t be needed as your screws will have to ‘Coriolis Spin’ backwards much like your opposite dunny/toilet bowls do
