Sandin A/C and compact P/S pump brackets

I know modern vehicles have the a/c compressor mounted very low but... they have a lot of shrouding too. I worry that this configuration in our classics would subject the a/c clutch to too much water, sand, etc...
I would prefer the compressor where the alternator is (refrigerant hoses on that side after all) but the battery tray is in the way of moving the alternator over there.
