How to: Short Nose Water Pump

I ran into a similar issue when I used a later aluminum water pump on my 1965 Dart 273. It is ~1" thicker than the correct cast-iron water pump. I only did so to match the only radiator Autozone could get, for a 1972 Dart w/ water pump inlet on the opposite side. I finally rigged a fan to fit, but no room for a clutch fan. That also led to fun with the belt routings, but finally got things to fit.
