I would like to put aircon in my 2wd cossie, gets pretty warm here in Queenstown, NZ over summer. wit regular 30 deg days (or more) Has anyone done this and what parts/effort required? I can get the bits from a contact in Spain from wrecked Sierras there for the same year (1988)

 

I did it many years ago in my 2wd saphire,you have to strip the whole dash out and cut a hole in the bulkhead,the rest i got the bits from a ghia sierra,and had to make my own mount up for the pump.Also changed the pulleys to a 4wd polly v setup. its a bit of pain but doable

 

I have fitted the bulk head piece on my 2.9 24v Sierra, there's quite a bit of info in my project topic.
