Correct upper coolant hose?
I was just helping a member with his 71 slant. It had the flex hose just like yours. I looked at the upper hose on my 64 slant but couldn't find a number. Anyway, I agree it should be real simple to fit. Looks like all you need is a 90 deg bend, but hard to tell in the photo. ChazRam's looks like one with a 90 deg and 45 deg in the horizontal plane would work. Just look thru rockauto at different cars, if they don't have yours. Most upper hoses are 1.5"D. Many rodders like a 90's Ford V-8 truck upper hose, since long w/ many bends and cheap. With 2 of them you can fit almost anything. Your lower hose is more challenging. I posted a number, but forgot (Gates 60377?). Same hose fit 3 of my Mopars different places.
