speedo cable 65/66 Dart 4-speed question

Need to replace a bad speedo cable in my '66 Dart (the end separated on the dash side). I have a '65 A833 4-speed out of a Dart. I've seen a lot of ones at local parts stores and online that say they fit, but aren't the same. Pulled one out of a '65 slant 6/auto Dart, not the same.

The only thing I've seen similar is an OEM advertised cable for about $150. Is there a cheaper one? Can the inner cable be replaced on a '65 setup with 4-speed (fitted into trans. with large o-ring)? The cable housing looks to be in good shape.

Mine looks like this:

A lot of threads and info on this topic but I couldn't find the one fitting my application. Any help is appreciated!
The cable you show is for a 65 Down car/trans application. Does your driveshaft bolt to a flange on the trans, or does it slide into the trans? If it bolts on, it is a 65 down trans, and the cable you show should work.
If it slips in , the trans is a 66 up, and you need a cable for a 1966 car.
I'm fairly sure the 66 cable is ATP Y-804 (63 inches long) or ATP Y-803 (83 inches long).
If you need the 65 cable, as far as I know, it is not "readily" available, but you can replace just the inner cable, if the housing is good.
