Clip holding arm in place for casement window

Question

The arm that allows the casement window to open or close is coming loose because the clip that holds it in place is missing. It's a very small piece and when it dropped on the ground, I couldn't find it.

Thanks for posting. It's a bit tough to tell from these photos, but this might be the 39-529 Track Slider, used with the 39-253LB and 39-253RB Dual-Arm Operators. Please compare and see if this matches what you need.
