When I had to replace one of the cables on my 95, 2 or 3 years ago, I think I found some very small cable at my local bait and tackle store, but would not swear to that. I can’t remember, either, what I used for cable ferrules. As Terry said, though, it is a PIA, and requires lots of patience and a good vocabulary! (I sure found just how limited mine was!) One thing I found handy in the process, though, was the use of the small Vicegrip pliers to act as a 3rd and 4th hand. As Terry stated above, only one cable at a time “pulls” the dial drum at a time, depending on direction of the shaft turn, while the other just maintains tension on the drum, as it unwinds. They should both be taut at all times, with no slack in either cable, or it will all come unwound into a small rats nest.
Perhaps, braided nylon fishing line would work, but I was afraid that it would stretch, over time, requiring a complete do over. I didn’t want to go thru this again. Good luck, and have fun with it.
