Bill, just came across your post. I had the cable problem and was confronted with the 50.00 fix that takes 10 weeks to happen and decided to take matters into my own hands. Went on the auction site and found a three pack of cables for 15.00

Not a hard DIY at all. Took all of half an hour. Hardest part was discovering the holes in the floor to replace the screws that hold the seat in place. By the way, these cables were better quality and now I have two extras 'just in case' or I run into someone at site that has the same problem.
