Thanks for posting! I believe your coil assembly can be replaced with the Series 140 Quick-Tilt assembly. Since yours is stamped with a 9, you'll need the S140-9.
Be sure to carefully review and compare the dimensions below to confirm that this assembly will fit in your window track.
I'm glad to hear that these are the right replacement for your coil balance assemblies.
I'm sorry to say that his hardware does not come with a set of installation instructions. We do have two tutorial videos below this thread that will show how to remove and install these assemblies. Take a look at them to see if they might help with completing your repairs.
My pleasure! Please don't hesitate to reach out with any other hardware repair questions or future projects you might have.
Have a great day!
