Integrated seatpost clamp problem

Hi
The two ears of the integrated seatpost clamp on my bike is little deformed because of the improper torque applied to tighten the binder bolt in the past. They are just getting too close with each other,so the bolt holes on the two sides are not paralleled and a new bolt can not pass through.
Any idea on how to solve the problem?
Thank you in advance for sharing your ideas.
