I just changed my cable this weekend. '75 Duster/ slant with 904, but I think it should be same. The one I took off was 63" and had a 1" hex nut, the one I put back on looked like the first one in pics above except no metal around the plastic. I got mine from Napa for $22. They call it a 68 inch, I measured 69. Just sticks out a bit more by the master cyl.
