Hello,
Unfortunately, we were not able to locate an operator with the same offset link arm you show in your photos. We do offer the 39-316 that attaches to the sash with a straight arm that connects to the 39-545 and the 39-546 stud brackets. We can't make any guarantees but you might be able to use this type of operator and brackets if you can't reuse the originals.
We also offer the 39-172 operator with the offset link arm. Take a look to see if this might be a better replacement option to use with the 39-560 and 39-561 clip-stud brackets.
Lastly, you could also order one of the operators that we mentioned and swap out the link arm with your original arm using the 62-014 Truth rivet. Review the specifications of each option to see if one of them could work for your application. Thanks for posting!
