Speedometer cable and the angle drive:, Speedometer cable has broken 2X by the angle drive Options

[PBC914]

I freshened up the transmission, and installed new seals in the speedometer drive side shift transmission on my 75 914.
After about 100 miles, the angle drive moved back toward the rear and bent/broke the speedometer cable.

I ordered a new cable, and moved and tightened the angle drive so it was facing toward the front of the car. After driving home today, it did the same thing and broke.

Is the angle drive supposed to be tightened so it can't move or is it supposed to spin freely when in place?

Anything else that could cause this condition?

Thanks!

Mine did the same thing, but it was caused by rotating the gauge vertical so I could see the most necessary mph numbers. Doing this introduced a bind that snapped the cable. I had to rotate the gauge, otherwise I was constantly dipping my head to see around the steering wheel to see my speed. To solve the bind, I shot the cable towards the glovebox, then looped it towards the firewall and then down to the tunnel. Fit like a glove and works perfectly.
