Need some help figuring out water pump/alternator solution

Stock components in good shape will work just fine. The housing with the drivers side inlet is the most common by far. The only thing I don't like about the factory setup is its crowded around the distributor. The alternator makes it so I can't use my big old Sears timing light.(really bright). I plan to move it to the drivers side soon. Anybody know if the factory ever mounted the alt. on the drivers side?
