Gorell window replacement part

We have series 5305 GORELL windows, 31.75 X 61-5 inch windows, tilt and slide type. The tilt out latch on the upper sash has become broken on a couple of our windows, and we need a replacement part. We understand SoftLite has taken over from Gorell, and we hope you can help us find the appropriate part, which is not shown in the Anatomy of a Tilt Window video.
