I doubt that part of tb is sold separately. Maybe you can see with yours whether you'd be able to buy one from a junk yard and replace just that part...or at that point, honestly, probably just replace the TB.
I'll check realoem, but as I recall, it's a single assembly.
Only other thought I have, not really seeing your 'break' live, is that maybe there's a way to drill a hole and 'pin' the end of the cable in there. As long as the ball on the end of cable is holding in there firmly, you should be fine...but I can't tell whether you have enough 'meat' left to hold it there.
