Gulf Stream wire rope repair on rear slide out

The steel wire rope on my 2005 straitened by gulf stream frayed out. The cable had a stop at the end that allowed it to slide into the bracket. I can't seem to find this stop or a way to crimp a stop to build. This video shows the stop at about 55 seconds in. Does anyone know where I can get this stop or how to make it?
