Broken sliding clip on Certainteed casement, swings left

We just replaced the glass and weatherstripping in our ~3 ft square Certainteed casement. We thought we'd successfully reset the sash, but on its 2nd open, the bottom sliding clip on the hinge attached to the sash was partially in and partially out of the window's track. In trying to release the window, the sliding piece bent and the plastic broke. We need a new part/set, I believe.

The top and bottom bars attached to the window are 7" with slightly extending curved ends. The part is marked Truth 31858.

Your help is very much appreciated.

Thank you!
