transmission cooler lines on a 904

Bought a 318 engine and 904 trans thats out of a 73 barracuda. Im putting it in a 59 Plymouth belvedere. The belvedere radiator wasn't any good so i found a radiator and was gonna use a separate trans cooler. The trans lines are from the stock tranny that came with the car they seem to fit im just stuck on which line goes where thanks for the reply
