From the moment I own  my 1965 Mustang I always had a wobbly speedometer needle. After examing the cable I also noticed the plug at the C4 was leaking, just at the connection of the plug and the 'plastic' cable. There was always a drop of atf oil. I found out there are two different cables, a 60 inch for the automatic and 3 speed, and a 68 inch for the 4 speed manual. So I ordered a speedometer cable for my 1965 automatic. When installed the speedometer cable (well lubricated), the needle was quite calm at about 35 mph to 90 mph. Faster I didn't try here because of speed control. Below 35 mph there was still a little wobbling. After some miles I noticed a ticking noise from the speedometer self. So again loosen the cable from the speedometer, more lubrication of the cable and the speedometer self. Put everything back and drive. Still the ticking came back. I disconnect the cable, pushed the inner cable more into the outercable. This helped for about 500 miles and the ticking came back. I also noticed the plug at the c4, connected to the cable, was starting to leak atf oil. Some glue and special tape on the connection stopped the leaking.


Left the new 64.6 inch cable, right the old 60 inch

 Maybe I had the wrong cable. So I measured the cable and this one was 64.5 inch, a strange length. Also the square end of the old cable looked more massive than the new one.
 
  So I was fed up with this cable issue. I start looking on ebay and found a NOS 1965 speedometer cable. Hoping this would solve my problem, I ordered the cable.




It was at a company called Cobranda, related to the Tony Branda store. They sell NOS parts and when it's not at their Ebay Cobranda store, they can look for the part you need. As Anthony, the son of Tony Branda, informed me.



When the cable arrived I found out that the cable was exact 60 inches, very, very stiff, and it wasn't easy to stretch the cable as it was rolled up for quite some years. The cable felt more solid than the ones I had.


There was also a six point nut, instead of the round one, for connecting the cable to the speedometer.



Ford encoding.

When I was having my first ride with the new cable I couldn't believe my eyes. The whole speedometer range from 0 to 70 mph, I tried for now,  the needle was steady. At 5, 10 or any other speed the needle was steady, no more wobbling. Not a little bit!
Although it was a pricey cable, it was worth every penny. For me at least.
