Hot rodders are famous for installing a mixed bag of parts. I install the radiator then bend a coathanger or heavy piece of wire to match the length and bends the hose needs to make. I also note the inlet/outlet sizes of motor and radiator. Then I take the wire to my local auto parts house and pick up several hoses that look close. Test fit the hoses and when one works return the others for refund. Sometimes you may have to cut an end or section out of a hose to get just what you need.
