Window Tilt Latch

Attached is the label on the tilt window and a picture of the broken latch. The latch is for the right side of the window as you look at it. The beige cover part is 2 5/8" long and 3/4" wide. The white part that inserts into the sill is 3/8" wide and the rectangular portion that fits into the sill is 1 3/4", excluding the triangular part the sets into the frame. There is a spring that also fell out of the window latch. Please let me know what replacement part I should order.
