'69 with a '72 318 - I need hoses

Experts! I have a '69 Barracuda w original radiator non A/C car - with a '72 318 in it and, I'm looking to replace the hoses. Flex-hose works up top but, I'd like to find a source for the lower hose... (1-5/8" I.D.). Anyone got a link/part number?
EDIT: Inflow and out on radiator are on the driver's side. W/P is aluminum - exit is on passenger's side.
