67 Impala 396 w/ AC

Looking for the stock setup pulley arrangement for the AC 67 cars. My engine is not original (454 '72 ish) and I am wanting to install a short water pump and mount alternator on the drivers side as original, with the AC on pass side upper. I'm wanting to make sure I use the correct matching pulleys for the crank and water pump.

So I think I need a 3 groove on the crank and a 2 groove on the water pump, right? I'm having trouble finding good layouts or pictures for this setup. Any ideas are appreciated.
