Torque Wrench Repair???

My old craftsman 1/2" drive torque wrench took a **** on me this weekend and started skipping teeth in the ratcheting mechanism. Any idea on where I can find a rebuild kit? Or would I be better off buying a new torque wrench?

In this picture, you can see some of the strips of metal that came out of the ratchet when I took it apart. This is for a Craftsman 1/2" drive clicker torque wrench (#44441).

Thanks!
