Peter,
I think I should explain it here as it might be of interest to others.
The idea of sandwiching the fans between the condenser and the radiator was so that we could maximise the size of the fans on the radiator (because the condenser is smaller than the radiator), and ensure that as much air as possible was forced through the radiator.
However, it may have been just as effective, or even more effective, to mount the condenser on the radiator, and have two big fans on the back of the radiator, pulling air through, and two smaller fans on the front of the condenser.
There's no doubt in my mind that mounting the fans directly on the radiator is far more effective than having the fans mounted in a cowl more than six inches in front of the radiator, which was the original Bristol configuration.
To be honest with you, I was talked into doing numerous modifications and it was so long ago I can't recall the justification for some of them - moving the radiator forward falls into that category. With hindsight I don't think I should have allowed this to be done, because I don't think it was really necessary and of course it is another step away from originality.
Thankfully I do still have the original radiator and mounting brackets.
The compressor in my later setup was used because it is the original compressor that would have been found on these Chrysler engines (I'm fairly sure it is what was used on the Jensen Interceptor), so the mounting points were already there. However, based on my experience I do think you would be better off using a modern compressor. My AC system is also from Vintage Air and it came with a Denso compressor. Having to fabricate some brackets shouldn't be a huge job - just getting the alignment right could be tricky.
Let me know if you still want me to call you to discuss further.
