2000 trans am throttle cable plastic connector

Looking at the throttle cable, where it is attached above the engine, there is a plastic connector that slides into a metal fitting to hold the cable in place. (Just beside it is the cruise cable of course). Today when I went to push the pedal to the floor, I guess I hit it too fast and it broke that little plastic piece, so now the cable is flopping. I have it attached with some "riggin" just so it is driveable, but I need to replace it.

Has anyone replaced just the plastic part, or is it an entire cable replacement?

Thanks,
Jeff

not 100%, but it may end up being a whole cable replacement.
