Been a while since I looked at one but if I recall correctly the end was crimped on. If yours pulled out of the end ( shifter end is flat I think ) then try to reinsert it and crimp again. Or if it will insert again but not crimp maybe silver solder it? Let us know if that works.

My son is finishing up his A100 - I'll take a look at his cable and see how long it is. I just may have an extra cable buried in the garage somewhere.
