I switched to a 3 core champion radiator and the hose I was using is now to long to reach the upper. I have a 73 dart sport with a 440. Anyone else have a similar set up know a part number for the upper hose?
For me, a Gates #20875 or Dayco #70539 is the ticket. I've used it on my BB Duster and am using the same one on a BB truck we're building. You trim the radiator end to length.
