Mel is more than likely referring to the mechanical cable that goes from the flaps back to the switch system. At least on the older ones like mine, there is a push/pull cable that goes from the flap cross arm back to the levers that control the flap position through a number of micro switches behind the flap controls. There is one on the front as well, just much shorter obviously.

I dont know if you are going to find one of those.....McFarlane will make any type of cable system you need, but it might not be FAA-PMA. You may have no other choice. Maybe this fits in the "owner fabricated" part or AC23-27 regarding part and materials substitution for vintage aircraft.........

Forgot to add that the replacement activity is actually pretty straight forward. You will need to remove the floor but the cable runs from the firewall, under the floor then up to the flap control levers. If you remove it and send to McFalane, they can easily make a new one as it has standard end fittings.

If you remove it you may also be able to work it loose by spraying penetrating oil through both ends, but not sure if you want to trust that fix. A frozen or sticky cable puts a lot more stress on that crappy little flap motor which costs a ton to replace.....
