Sash Pivot Shoe

I am looking for a sash pivot that is similar to another one of your products but mine have a metal insert that the fold in windows (top down bottom up) pivot in. The issue is the white metal has broke in a few of them and no longer supports them in the pivot aspect without them popping out of the support. So it makes it hard to flip them into the house to wash the outside. Do you carry something like this?
