TORQUE CONVERTER WEIGHTS

While doing exhaust on my car I happened to look at the torque converter and noticed the counterweights were missing. They were either removed, or fell off, I am not sure. I would like to find a set of them to replace the missing ones. They are the 2 rectangle shaped weights, there is still an outline where the once were, so I can just weld into place. I am looking for a set to purchase, or weight and dimensions so that I can replicate them.

thanks
