[AC compressor on VG30E]

I have a 1970 Datsun 521 with a  1985 Z31  300ZX N/A engine and drivetrain.

Because of the small cabin I would like to add airconditioning to my car. 

I would like to use a vintageair system, and am doing some research into how to get a ac compressor to work.

 

As far as I can tell a Z31 never had ac from the factory, is this correct? 

At vintageair they recommend a Sanden SD 508 compressor. Is mating this type of compressor to a VG30e doable?

Thanks in advance for your kind responses. If any of these questions seem stupid, please excuse me. 

I am new to this type of car and engine.
