I have a later 5.0 Mustang engine with a reverse rotating water pump. I'm looking to eliminate all the belt driven accessories except the alternator and water pump. I'd have to figure out some sort of idler pulley to keep the water pump reverse rotating. If I get a standard rotating water pump, will I have to change the timing cover also? In other words, do both style water pumps use the exact same timing cover, or are the covers unique to each pump?

Thanks!!!
