71 Cuda 383 auto. The rad hoses are both on the drivers side. Its a 22". I want to replace with an alum rad, but most of the bottom hose locations are on the pass side. The top is not a big deal, just a hose change, but the bottom, is a water pump housing change. Did they make big block housings with the outlet on the pass side?

yes but they are cast iron , should be no problem finding a rad with the inlet on the right side ?
