Here is what I have. no visible manufacturer stamps that I can see. Looks Identical to the one in post #'s 20 & 22

JohnnyC alerted me to this thread.
Here are some pics of the one from the downey catalog that he posted,
Well I like the one in the first post the best. Very simple, someone should re-produce a duct with an evaporator in it that goes in between the original fan and heater unit. We don't need a temp control knob, just an on and off. Switch the heater to vent, flip the AC switch and turn on the fan. Rather than an expansion valve a fixed orifice tube would be simpler with a pressure switch. Another idea is to take the original rear heater and have the ends converted to an o-ring type connection which would allow you to run freon through it instead. In all seriousness you might be able to get away with not even converting the ends. The evaporator part of an AC system is low pressure anyway-like 30 psi.
Bump..
Has anyone seen one of these before?
They both feed directly into the heater unit but It looks like Zimmi's has some kind of add-on adaptor to the heater unit so that air can directed. Mine is just the stock unit. From memory mine is a Sandon compressor.My mate Pete @84TROOPY has that same a/c unit @Zimmi in his 11/84 HJ47. Our government [at the time] telco Telecom took delivery of the truck from new, and it's identical to yours. Except the switch is up on the dash fascia to the left of the 4WD light.
Won't you still need a pulley for the ND?Yup mine is a sandon compressor as well. I picked up a factory Nippon denso ac unit today I'm thinking of swapping it out because the current setup hasn't run since Iv had the vehicle because it is missing the pulley to run the compressor etc
Here are the rest of my switches

I know I'm only a year or two late but I have this ac in my 84 hj47 and have the documents that came with it.
