The PCV hose currently sold has a C6AX-6A664-N part number stamped on it (which makes it incorrect for 1965 as well), but you can either remove the stamping, or remark it "XE-112634" which is what is shown in the 64 Ford Engine Equipment Manual, page 45; and cut off the bend to the 90 degree PCV valve you have. Two clamps, 97331-S8 are shown as being required. The "XE-" number is a preliminary engineering number.

Change the part number to C6AZ-6A664-N.
