Moderators, if you know of a better place to post this, go ahead and move it. I thought it might get more exposure here.

My son has an '72 Chevy/GMC truck that has busted the spider gears (each one is missing at least 2 teeth) <img src="/forums/images/graemlins/shiner.gif" alt="" /> in the rear end. It has an H072 (14 bolt) rear end in it. Does anyone know where I might be able to find spider gears for this rear end? It has 2 spider gears and that is it, otherwise a pretty well built differential. He's thinking about welding them, but neither he nor I can find gears. I believe this was an Eaton product for GM, I also believe that '72 was about the last year for this rear end, so we may be out of luck. Any help would be appreciated. Thanks in advance.
