Re: GTV6 AC/compressor questions

Chris,

Thank you for your answers. I think the A/C was the same in Europe and in 
the US (at least the heater box looks the same and It also had the York 
compressor). The tropic air is probably something specific to the US, since 
my A/C comes from an '86 GTV6, and there is no sign of second evaporator/fan 
(perhaps because Switzerland is not what one would call a "tropical" 
country...).
Concerning the R12, it is getting more and more difficult to find, since it 
is no more produced. Anyway, this is not the point, and since sooner or 
later it will be practically impossible to find, I want to do the conversion 
now, as my A/C is out of the car.

By the way, I think I found an interesting alternative for the compressor. 
It is a Seiki-Seiko from, I think, a 155, and it just needs a minor 
modification to fit into the 75/Milano brackets. It would also be necessary 
to replace the clutch, since the belt is different. The good thing, is that 
it is a R134 compressor, and it should make the conversion easier. The only 
thing I would need to know is if the filter/dryer is compatible with R134.

And finally, I would like to install the A/C this week-end, so could someone 
give me some answer about the following question?
