but I went to make a tension adjustment, with the locking screw loose, and one tong just broke.



I HATE when that happens

I understand, but like I said, not a rare part to hunt down. try the Moparts parts section, or maybe ebay for a cheap parts carb that has the items you need, never hurts to have a spare around for other parts anyway. You might find that NAPA or other parts stores has something that will work as a replacement, but it will likely look a bit different.

Good luck!
