Fixing my belt routing

To me the extra pully on the alt is no big deal. (you only have to use one) Going with only one belt to run everything my not be a good idea due to stress or slippage. "I" would use one belt from the crank that lines up with your PS. The other belt, for your ALT and Water pump together. It looks like (from the pic) your water pump will not line up? If thats the case you can get a deeper water pump pully that will line up with your ALT and Crank. I can't see where your PS belt would go and line up with which pully on the crank.
