Hemi engine with motor plate

Everything I've read and seen says 3 1/4" to the passenger side. I had to shim my passenger side for clearance and mine is 3" offset, but I figure that is close enough.
Where are you getting your motor plate, and do you have a car cover on the hemi??
I am looking for a motor plate that will allow me to use a stock belt driven water pump on a car cover setup.
