Replacement Tilt Latches Needed

Im looking for a replacement tilt latch as shown in the attached pictures. The windows are about 10 years old, all vinyl, and no indication of the manufacturer that I can find.

The dimensions of the latch are 3/8" thick, 11/16" wide, and 2 - 3/8" long. Length measurement does not include the wedge shaped piece that retracts.

The slot (see picture TiltLatch_Window) is 9/16 wide and 2 - 7/16" long.

The latches snap in - no screws are used to attach it.
