Any one fitted Air Con?

As Stephen says, doesn't matter too much.

Use the largest condenser you can fit in front of the radiator and leave at least 25mm gap between them.

The usual problem with all modified systems I've seen tends to be not enough cooling through the condenser, particularly when switching to later 'green' refrigerants.

Funny how some ideas change when The Boss puts her foot down isn't it!
