help identify this part

A contractor from Wadsworth, IL 60083 says:
The white part on the left of this picture is what I ordered but it does not fit.
The part on the right is the actual part I need.
The only tag on the window jamb is shown in picture #2 but I cannot identify the manufacturer of the window with this information.

Tom from SWISCO responded:

I think your window is Simonton brand, which would explain why the 15-192 that you bought from us didn't work, since it's Certainteed. The 15-192 actually can technically work but it requires a lot of adaptation that most customers I speak to don't really want to do. 

So, I have good news and bad news. The bad news is that Simonton doesn't actually make this coil balance assembly anymore and I don't think you'll find an exact match on the market.

The good news is that we have an easier solution. Rather than break it down for you, I recommend that you watch the video below. This is a very thorough step-by-step guide that will tell you exactly what parts you need, how they work, and how you need to install them.
