broken end of cable that pulls sliding rear window

[sunset beach guy]

how can I repair a power sliding rear window?  the little "nub" on the end of the cable came loose where it fits into a hole that attaches to the rear sliding window.  Very poor way to connect that cable to the window but it is what it is.  Can anyone come up with a way to remedy this situation?  I thought of a old time choke cable stop (with a screw) but that is too big to fit into the hole
