Broken part needs replacement

Question

Plastic (or nylon?) insert is broken on one side of window frame. These are photos of the unbroken part. It is a rotating fitting. The metal "ears" at the bottoms of the top window sash are inserted into the rotating fitting.

We believe your pivot shoe's width is 1-1/4" by 9/16" thick. However, I'm afraid your pivot shoe has been discontinued. If you could take a look at our 15-118 pivot shoe and confirm those measurements we gave you, then you may be able to use this a replacement. Let us know how you made out.
