65 Dart Speedo cable replacement

Replace the o-ring and pinion seal on the original metal shielded old style speedo, putting it back in I noticed the cable metal sleeve had split into and the speedo worked erratic with noise at the speedometer. I shoved it up in the transmission, smoothed out but the noise persisted.
Last night the speedo started to sing and pegged at 120 and beyond.
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?

Pretty sure the same speedo cable works for manual and automatic
It says fits GM, Ford Mopar pre 68. Did all makes use this same speedo? Can't be!
