Here's a view of the lower radiator hose as I'm rough fitting it. The water pump end is a 2" hose fitting and the radiator outlet is 1 3/4". The lower hose leaves the water pump headed down and must make a quick 180 to come up and clear the front cross member. It then needs to make a left 90 degree bend to go around the steering shaft. It then makes a reverse 45 and goes into the radiator (yes, I know, water flow is actually the other way, but it's easier to describe this way).
