I'm trying to restore my 1976 TerryBass fiberglass boat and need to replace the steering cable. It's not a Ezy-Glide because they say they didn't start up until 1981. The cable is smaller in diameter than modern cables used today. I can't find any labels in the stick steer lever box or the cable. It needs to be 12' long. I know I can replace the whole unit with a new Ezy-Glide but I'd like to keep it original as possible. Anybody have a solution?
