Okay, so after I answered I went back and re-read the original post again and the reply that a 66 vintage cable will work to hook the 65 speedometer to a 69 trans is correct. Sorry, I got sidetracked by my frustration finding correct gears for my 65 stuff. Anyhoo, I went and took a pic of the tranny end on a 65 and previous years tranny, it's tacked on here.
