Part of my restoration in my '71 is to update the A/C to a more modern system, so I got a new Sanden 508 compressor and a parallel flow condenser, the rest is all stock (except the upgraded POA valve). A friend told me that it would be better to install a VIR eliminator to the system since I have a new compressor that should work fine with a CCOT (cycling clutch orifice tube) system. I really liked that idea, but I dont know if my stock evaporator will accept the fittings of that kit, do you think its worth trying?? .. I'll be happy to spend $150 if I will have a better A/C.
On my 73, I used the Sanden. I did away with the VIR system by changing the evaporater and dryer to a 79 model. every thing bolted
up. I have been running it for 3 years in S. Florida, 50,000 miles with no
problems, it works great.

While on my '72 with the expansion/POA valve he already has, same setup, I have the import compressor off a '88 serp setup, and running with the stock components and 134...works fine, and I don't have that irritating on/off crap from the compressor all the time clicking in and out....just seems better to me....

you mean you used the stock '79 components?? .. whats the setup used on '79??
This is with regard to converting a '73 a/c car to modern a/c:
you need a #4709 Sanden Compressor ($200)
compressor brackets from alangrovecomponents.com ($90)
a '79 evaporator ($250-300) - bolts right in
orifice tube for the evaporator ($2.00)
use factory condenser
Custom Hoses from an a/c shop ($?) - haven't done that yet
Uses no "expansion valve"
and I don't have that irritating on/off crap from the compressor all the time clicking in and out....just seems better to me....
I could be mistaken but if he switches to the Sanden compressor and does away with the POA valve I don't think he would have the drag on the system that the A6 system does that makes that anoying on/off.
Thats why I'm so interested in a CCOT system, because the Sanden compressor will not drag the engine while on/off cycles.
If no one else chimes in you could also pm forum member Brandywine. He has an 82 which is a little different to start with but I believe he converted his system using the Sanden unit.
I did the same conversion on my '73 as mentioned above. I paid less for all the parts except the AlanGrove brackets. Compressor off Ebay and evaporator from Arizona A/C ordered on line. Mine still does not cool as well as I would like. Did you guys stay R12 or go R134 as I did. Also had my hoses made and system charged at a local shop, cost close to $400 for that.
When I look back at what I spent and compare to a Vintage Air setup I wonder if I would not have better off with that.
Also if you have POA I don't think you have the VIR setup.
