Speedometer cable for 1965 Plymouth Barracuda 273

Professor Fate is correct I believe! the double screw on will fit the later trans to early speedo, I think his is actually the real deal date correct. After 67 did they go to a bayonet speedo mount?

Ive used the cut to fit. My first one I cut it too long and the thing was binding up in the sheath and making the speedo wiggle. The 2nd one I cut just a hair shorter and it has been working ever since. Use graphite powder (lock lube?) as the lube not grease or oil as that collects garbage. I was suprised how gritty the old cable was when I pulled it it, where did all that stuff come from?
