Aftermarket AC Condenser Install

Hey FABO,

I'm looking for some advice about installing an aftermarket AC system.

Car is a 70 Duster.

I have an AC system that came with a 12" electric fan for the condenser. The condenser fits, with no trouble, in front of (towards the grill) the radiator.
The radiator is also aftermarket with electric fan.

Is the condenser fan absolutely necessary, or will the rad fan and the position of the condenser on front of the rad be enough cooling?

With the fan and condenser, it extends into the space for the radiator about 2".

Alternately, I guess I can make 2" spacer brackets for the radiator mount to push it back. But I don't have the engine in yet so I can't check for clearance.

Thanks for any replies.
