65 Dart Speedo cable replacement

{SNIP}
I hope it is just the cable.
Now to find the old style, where it is one piece. not the newer 2 piece.
Will this work?
American Powertrain Speedometer Cables SPUN-20001
Saw in another post about speedo bounce... LUBE THE CABLE!
So, with the speedo already disconnected behind the dash, got out the old Silicone Spray, and shot it a few times into the cable housing, letting a few seconds in between to let it soak in. Wish I had better angle.
Hooked it back up and took her for a spin.
Bouncy at first, with the usual noise it had since I got it running a year ago. As I drove it it smoothed out more and more. Noise started to get less.
Still bouncing a little at really slow speed.
Now to spray the back of the speedo this time! Duh!
I didn't think this was going to work, so I didn't attempt the speedo.
Who knew!
I got a Speedo again. KNOCK ON WOOD, GOLD & MY ****!
