Speedometer cable weirdness

I just looked through 110 different cables by ATP Automotive. The Y 804 comes in at 63 inches, and appears to have the correct fittings. But what about this: can I pull out the new inner piece, cut it to size, and then put in into my old cable conduit?? Can that inner portion be cut??
Absolutely, and they even make universal cable repair kits that come with a long inner section and a tool to put the square on the end after it's cut to length.
