K guys
My M8 got back to me with some suppliers for the generic A/C parts.
Heres a copy of his mail:
Look up
http://www.jayair.com.au, they are the biggest wholesaler / importer of A/C bits into Australia by a long shot.
Ram-Air in Melb makesengine mount kits or Jimmy Russel at AKTF in Taren Point (Sydney) (aka The Kit King)
Also look up
http://www.ingram.com.au
or

He didnt sound too confident of finding a RHD version of the ducting unit tho.
To make a duct unit. Probably the best way is to glue together sandable foam sections and cut and sand to the shape you want and use that as a plug mould to make a fibregalss mould for the duct unit.
Its a pretty time consuming and costly process tho but the results are really worth the effort as you can fabricate the ducting to look however you like foir that "Original Equipment" look.
Witness some of the stunning custom dashes and consoles the rice boys fabricate for their japper vrommpssht doof doof cars. Amazing!
Whoever ends up doing the job will get his money back many times over by selling copies of his ducting.
This is how we used to do custom integrated A/C installations.
We used the same (sandable foam) method to fabricate custom evaporator cases on cars that never had integrated A/C in the first place.
However, the issue of ducting is really a personal one and having a universal underdash evap/blower unit with thestock aimable louvres sited centrally in the car will provide plenty of cooling air in the confines of a VW cab without looking too "aftermarket".
There are universal bezels that replace the louvres on a traditional underdash evap unit that simply have (something like) 4 x 2.5" round spigots which you attach flexible ducting that you can run to dash vents sited wherever your little heart desires.
This would allow you to mount your underdash unit high and right back under the dash and the flexible hoses can be hidden from view to give some semblance to an integrated A/C system.
This arrangement would save dozens of hours of tedious fabrication, sanding and filling as well as glasswork chasing a custom ducting setup.
It also give you the option of running one outlet up to the demister vents for superior winter defogging.
Best of luck with it tho.
