The arm which connects to the stud on the window is longer than the current broken part. Everything else is exactly the same. Is there another part or do I need to install the new stud bracket somehow?

Hello,
Thanks for your post. This window operator is a match for the 39-187 Sash Dyad Crank. I'm confident this should be what you need but be sure to double check the dimensions and design to confirm it is a match.
The compatible hardware and accessories can be found tagged below this thread.
