So I search until I was tired. I am lucky to have a parts truck with a good nylon cord for my 91 FJ80. I plan to just buy the new mast and switch the entire unit to my good truck. Only issue is how in the world those the original mast unscrew? Do they get tight over time? two sets of plyers and a lot of sweat yet it will not come loose. I am concerned i will break the 30 year old nylon cable I am trying to save. Thoughts? Would heating it help? What is the trick here.
