Agreed, and depending on that water housing, the radiator lower hose location must then match.

It might be best to get the AC compressor and the brackets, and mount it, then see what pulleys you have and how they align.
Then you can find out what pulleys you need to find.
Compare them to online pictures of loose/complete engines and start to familiarize.
Fortunately for you, I have an assortment of pulleys, and most came from AC cars, I could sell you some at reasonable cost?
Unfortunately, I cannot tell you what ones would work for you, but we can work thru that?
