Are the female threads plastic or metal? I have never seen one of these in the flesh but I'm pretty sure either way it could be repaired with possibly a "threadsert" repair kit for metal or a good quality plastic filler for plastic car and motorcycle body parts which would require drilling and tapping new threads. First you could also heat up a proper sized threaded bolt and try to melt new threads into place. May be a little tricky but possible.
