    I know I looked it up once before however searching didn't work out. Can anyone confirm the upper and lower radiator hose part number for my '66 Coronet 383-4 barrel with 26" radiator (no A/C)? Trying to get my new beater on the road, thanks for the help!

      I ended up using a Gates 20511 . Its shaped a little closer to OEM , But not 100% dead on .
      I am still working on finding one shaped much closer to the original

        This is 20875 but I just realized you asked for 26” rad. This is a 22” C body rad in a B-body so the upper outlet may be in a different spot but I don’t think so.
