V belt routing

[Cdubvw]

Hello, new to the world of American cars and am having some trouble figuring something out. It seems as there are a few different options for accessory mounting depending on water pump styles. I am battling an annoying very loud squeel that begins at 2.3K Rpms and does not quite down. My belt is new but I feel like it is not routed correctly. The alternator has 2 pulley groves and it is running the outer grove to the power steering pump to the center crank pulley and ends on the inner water pump grove. There is 1 belt running everything. The truck has ac but it not running the belt due to a seized compressor. Crank has 3 pulley groves water pump has 2 power steering has 1 and alternator has 2. The alternator is mounted on the drivers sid and the ac compressor on the passenger side. Does this seem correct? Vehicle in question is a 71 suburban that started life as a v6. Thanks !
