You are correct, I have the stock same set up on my '72 Dart, but mine is factory, looks like you will be going aftermarket.

Trying to make it stock, just rebuilt the compressor, located the factory hoses, hard lines , new dryer and restored the a/c box under the dash. I started with nothing in the engine compartment. So I assume I will need a 3 belt setup?
