Pulley alignement question

I'm having some trouble getting everything to line up with my pulleys. Motor is a 360 magnum. Im using a slant 6 alternator. I was handed everything else as far as brackets and pulleys in a bucket and was told it would work but it dosent to all line up. It appears to me the water pump pulley isn't deep enough and seems to be sticking out proud of the alternator and crankshaft pulley. Do they make a deeper water pump pulley like 3 inches deep This? This one seems to measure 2.75 in deep but dosent seem to be enough. Or is there something else I have wrong. Thanks in advance

Here's pics if they help

Can you show some pictures of the alternator and brackets from the front also, and some zoomed out a little... What water pump pulley are you running???
