The flexible drive cable has broken off in the curved alluminum tube.

About a 3in piece of it anyways ..

I have found where to buy the replacement cable .. but .. I dont
know how to get that broken piece out of the housing.

the ground end of the housing has a threaded 2in piece sticking out
of it with a 11/16 nut at the base of it. But .. that nut will NOT
unscrew, I dont even know if that has anything to do with taking it apart

thanks
mike
