Since the end of the wire is probably essentially a brass washer with some plastic/rubber encasing it on the edges, you could probably drill or cut through the lead portion fairly easily. You should be able to pick up a new "bolt" at the auto parts store.

Essentially, don't worry about destroying anything except the cable and cable end. And even if it came down to it, you could even destroy the cable end. You could also buy a new cable end if necessary.
