What happened to the locking mechanism? About a year ago the cable that retracts the lock into plastic cover when the slide is extended, broke. I finally fixed mine by taking it apart, and using 150 lb test stainless fishing leader. I also had to replace one of the the small cloth covered springs. I got all of the parts through Beaver Coach sales in Bend. You will have to get the black plastic rivets from them too to reattach the plastic cover to the stainless mechanism. The retracting cable does not have to be that large, because the only pressure on it comes from the two small springs. I had the guy at the fishing shop help me with crimping the fishing leader with their special tool. So far so good. On the other hand, if its the actual locking cable that broke, then you will probably have to go with a larger cable.
