Confused what to do with a 5.9L serpentine setup

Here’s my 68 barracuda with the van bracket and magnum 5.9 truck brackets on everything else (it’s the ac delete alt bracket). Works great. I did relocate battery to trunk, which I assume you will too with your build.

I love your set up and that's exactly what I want. Unfortunately with LA heads, I don't have the required holes to bolt up the Magnum stuff anymore. I am kinda stuck converting to a LA timing cover/water pump so I can run the LA serpentine stuff that bolts to the water pump.
