Thanks for posting. If the operator itself is undamaged, and its just the stud on the stud bracket that the operator attaches to that is broken, then check out our 39-509 or 39-510 Stud brackets. If the operator is broken, see our 39-031 and 39-032, or our 39-155 and 39-156. These sets are very similar, with just slight differences in the lengths of the split-arms, so compare both with your old hardware to see what matches best.
