I would run the idler that replaces the PS pump and a shorter belt if it was me. I've never even looked for an electric water pump for the Hemi, do they make one?
Here is the bracket that bolts to the DS cylinder head and replaces the PS pump.
O nice one!!! that will work and nice and simple didnt realise they make a delete for the power steer as a stock item. Another part to add to the list haha
