Speedo drive gear demolished!

If the cable was binding, it would twist the square end off of the cable down by the trans.
I installed a new Classic dash and Autometer gauges. The adapter supplied to screw on the back of the speedo was binding the spinning internals of the Autometer gauge. Twisted off two cable ends before I found the problem. Classic dash verified the problem, remachined the adapters. I pulled the speedo gear to verify it was not damaged (43 tooth gear). Gear was ok.
