66 Speedometer Cable Route

Hey everybody, I've had the worst luck with my speedometer.
My first cable was original but the end that goes into the speedometer got damaged when I was out on a test drive and didn't connect the speedometer. Since then I've gone through 3 cables, all of them snapping from the inside. The replacements were all from autozone.
It is the original speedometer. I could swear I'm routing the cables the same way as the original one. I was wondering if anyone else has had any luck with these reproduction cables and consequently how do you route it? It has the original auto transmission as well.
