GM part 26072753 superseded the 26069709. Assuming you have RPO UK3. It's part number 26072752 if you don't. Hard to find as well.
I used to have a slew of extra 4th gen Camaro parts after I sold my '02 SS, and had a spare GM clock spring, but that sold pretty quick when I put it up for sale 10 years ago.
Unfortunately, it's likely going to be a used unit. New ones are like unobtanium. Good luck with your search.
