Will this bracket fit your Powermaster 37293 and your Powermaster Street Alternators 17294

Can you flip it for passenger side mount, looks like it would, and with it's low mount (if you run a water pump) is there enough lower pulley wrap to prevent belt slippage? I'm running a 6/71 Blower on my engine, and don't want over heating problems, caused by water pump slippage, I have space for a double water pump pulley, if slippage is a becomes problem.
